Specification Notes

1.) VBIAS = +5Vdc, PGND = LGND = 0V, BIN = 0Vdc, TIN = 2.5Vdc and SN = 50Vdc.

2.) Leakage current measured from SN to PGND.

3.) Guaranteed by design. Not tested in production.

4.) When either logic input (BIN or TIN) is at the low input voltage level the associated output (BGATE or TGATE) is guaranteed to be OFF (high impedance).

5.) When either logic input (BIN or TIN) is at the high input voltage level the associated output (BGATE or TGATE) is guaranteed to be ON (low impedance).

6.) Parameter measured with a 10kΩ pull-up resistor between PG and VBIAS.

7.) PG is at a low level when VBIAS is below the UVLO falling threshold level or the OVLO rising threshold level. PG is at a high level when VBIAS is above the UVLO rising threshold level or the UVLO rising threshold level. Refer to Figure 5.

8.) PG is an open drain output referenced to PGND/LGND.

9.) VBIAS levels below the UVLO- and above the OVLO+ thresholds result in the low side and high side gate drivers being disabled: The logic inputs to the drivers are internally set to a logic low state (i.e. OFF) to prevent damage to the external Freebird eGaN® HEMT power switches.

10.) The high side gate driver utilizes a bootstrap capacitor to provide the proper bias for this circuit. As such, this capacitor MUST be periodically re-charged from the VBIAS supply. The time tpcg is the minimum time required to insure that the bootstrap capacitor is properly charged when power is initially applied to the FBS-GAM02P-C-PSE Module.

11.) The minimum frequency of operation is determined by the internal bootstrap capacitance and the bias current required by the high side gate driver circuit.

12.) In order to keep the high side gate driver bootstrap capacitor properly charged it is recommended that the maximum duty cycle (ton/fs) of the top power switch is limited to the value shown. Consequently, the high side switch is unsuitable for DC applications.

13.) The shoot-through protection is activated if both the BIN and TIN logic inputs are set to the logic high (“1”) condition simultaneously. If the BIN and TIN inputs are activated simultaneously and BSEN is connected to BCON and TSEN is connected to TCON then both BGATE and TGATE are LOW (i.e. OFF).

Typical Application Information

The following figures detail the suggested applications for the FBS-GAM02P-C-PSE Module. For all

applications, please refer to the Implementation section, following, for proper power supply bypassing and

layout recommendations and criteria. In any of the following applications, the external HEMT transistors are

Freebird eGaN® power devices, appropriately rated for the voltage and current requirements of the application. If an

inductive load is driven then an appropriately-rated Schottky rectifier/diode should be connected across the

load to prevent destructive flyback/”kickback” voltages from destroying the external HEMT power switches. To

keep power losses low, it is recommended to use a Schottky diode with the lowest possible Vf and Cj ratings.

In all the following figures only the pins that are considered or that require connection are identified.

Recommended External eGaN HEMT Power Transistors

The recommended Freebird eGaN® HEMT power transistors for various power supply voltages (Vdd) and

load currents (Id) for the Qext, Qext1 and Qext2 devices shown in Figures 6, 7, 8 and 9 are shown in Table I.

Please note appropriate de-rating guidelines should be used in space and mission-critical applications.

100 30 FBG10N30BX 9 FSMD-B

The FBS-GAM02P-C-PSE is capable of driving any of the devices shown in Table I without modification or

additional circuitry.

Power Good Output (PG)

The FBS-GAM02P-C-PSE incorporates a Power Good (PG) sensing circuit that disables both the low

and high side gate driver outputs (BGATE and TGATE) when the +5V gate drive bias potential (VBIAS) falls

below an under-voltage threshold, typically 4.25V, or rises above an over-voltage threshold level, typically

5.60V – refer to Figure 5 for the proper operational nomenclature and functionality versus the state of the

VBIAS power supply. During the time when the VBIAS potential is outside of the pre-set threshold(s), the PG

output (Pin 5) pin is logic low (“0”). Alternatively, when the VBIAS potential is within the pre-set thresholds the

PG pin is logic high (“1”). The PG pin is an open drain output, so for proper operation the PG pin must be

pulled-up to VBIAS external to the module with a 10kΏ resistor. The logic condition of the PG pin may be

sensed by an FPGA or Microcontroller/DSP in order to determine when the external eGaN® HEMT power

switches may be driven with a pulse-width modulated (PWM) input signal(s) at the BIN and TIN logic inputs. If

either the under-voltage and over-voltage protection features are not required or desired, then these may be

disabled by connecting the UVA/*SD (Pin 6) pin to VBIAS and the SD pin (Pin 7) to LGND, as shown in

Figure 10.

Figure 10. PG Protection Function Disabled

“Shoot-Through” Protection

The FBS-GAM02P-C-PSE is also provided with a “shoot-through” or cross-conduction prevention circuit that

must be utilized when the FBS-GAM02P-C-PSE is connected as a half-bridge driver circuit. If both the BIN

and TIN logic inputs are asserted to a high (“1”) logic condition simultaneously, the top and bottom gate driver

outputs are commanded to a LOW output state (i.e. 0Vdc). This action prevents destructive, uncontrolled

current from passing from VDD through the two closed, external low ON-resistance eGaN® HEMT power

switches. If the FBS-GAM02P-C-PSE is connected in the Half-Bridge configuration (where the external top

and bottom eGaN® HEMT power switches are connected in series as shown in Figure 9 and are closed

alternatingly), then the BCON (Pin 15) pin MUST be externally connected to the BSTP (Pin 16) pin, and the

TCON (Pin 18) pin must be connected externally to the TSTP (Pin 17) pin as shown in Figure 11.

Shutdown Inputs (SD and *SD)

The low- and high-side power switches may be disabled (set to their high impedance OFF state)

utilizing the SD or *SD inputs, as shown in Figures 12 and 13. To disable the FBS-GAM02P-C-PSE module

gate drive outputs, the SD (Pin 7) input may be driven by an open drain or open collector that pulls this input

to the VBIAS supply pin (Pin 4). Alternatively, the module may be disabled by driving the UVA/*SD (Pin 6)

input with an open drain or open collector that pulls this input to LGND (Pin 3). If the SD or SD* functions are

not required, these pins should be left OPEN (unconnected).

PGND Pin (Pin 14)

For proper operation of the FBS-GAM02P-C-PSE, the PGND (Pin 14) pin MUST be connected directly

to the “Source Sense” connection of the external eGaN® HEMT power transistor for low side and Half-bridge

application circuits. For single high side applications, pin 14 should be connected directly to the system

ground.

N/C Pin (Pin 9)

Pins 9 is not internally connected. However, future revisions of the FBS-GAM02P-C-PSE may

utilize/exploit this pin for testing and added functionality purposes. This “no connection” pin is recommended

to be grounded as good engineering practice to avoid coupling unwanted noise into the internal circuitry of the

FBS-GAM02P-C-PSE. It is recommended that this grounding be accomplished using an 0805 size “Zero

Ohm” jumper resistor such that future revision FBS-GAM02P-C-PSE devices with internal connections to pin

9 may be accommodated by legacy PCB layout designs by omitting this jumper resistor.

Recommended VDD-to-PGND Power Supply Bypassing

The power supply pins and return pin of the FBS-GAM02P-C-PSE require proper high frequency

bypassing to one-another in order to prevent harmful switching noise-related spikes from degrading or

damaging the internal circuitry in the FBS-GAM02P-C-PSE module. It is recommended that a 1.0 microfarad

ceramic capacitor and a 0.1 microfarad ceramic capacitor, each 25V rating, be connected between VBIAS

(pin 4) and PGND (pin 14).

Radiation Characteristics

The FBS-GAM02P-C-PSE intended utilization is as a development vehicle for our future hermetically sealed radiation hardened ceramic version (noted by Freebird Semiconductor as the FBS-GAM02C-R-PSE or the current available, FBS-GAM02P-R-PSE (Epoxy, Over-Molded- Commercial Space Version).

Radiation hardness assured device to this data sheet (under identical form-fit function) is the FBS-GAM02P-R-PSE:

• Freebird Semiconductor FBS-GAM02P-R-PSE incorporates internally utilized eGaN HEMT technology designed, fabricated and tested per Mil-Std-750 Method 1019 for total ionizing dose validation with an in-situ Gamma Bias for (i) VGS = 5.1V, (ii) VDS=VGS=0V and (iii) VDS=80% BVDSS.

• Under the above prescribed conditions Freebird Semiconductor can guarantee full parametric data limits as outlined within the FBS-GAM02-P-C50 datasheet with pre/post radiation effects guarantee under a best practice commercial screened reliability level.

When incorporating Freebird Semiconductors radiation validated HEMT materials the FBS-GAM02P-R-PSE series are then “guaranteed by designed” to survive High Dose Rate TID to levels of no less than 100 kRad (Si) with minimum Single Event Immunity to:

~Heavy Ion: Au, LET= 83.7, 2482 MeV, Range = 130um
