per !esign concept%

voltage! If you don't use diodes, you could burn out your transistors.

Transistors, being a semiconductor device, will have some resistance, which causes

them to get hot when conducting much current. This is called not being able to sink or

source very much power, i.e.: Not able to provide much current from ground or from plus

voltage.

osfets are much more efficient, they can provide much more current and not get as hot.

They usually have the flyback diodes built in so you don't need the diodes anymore. This

helps guard against flyback voltage frying your ". To use osfets in an #$%ridge, you

need &$hannel osfets on top because they can source power, and N$hannel

osfets on the bottom because then can sink power. N$hannel osfets are much

cheaper than &$hannel osfets, but N$hannel osfets used to source power re(uire

about ) volts more than the supply voltage, to turn on. *s a result, some people manage

to use N$hannel osfets, on top of the #$%ridge, by using cleaver circuits to overcome

the breakdown voltage.

It is important that the four (uadrants of the #$%ridgecircuits be turned on and off

properly. +hen there is a path between the positive and ground side of the #$%ridge,

other than through the motor, a condition eists called shoot through. This is basically a

direct short of the power supply and can cause semiconductors to become ballistic, in

circuits with large currents flowing. There are #$bridge chips available that are much

easier, and safer, to use than designing your own #$%ridge circuit.

H-Bridge Devices

The - /0 has #$%ridges, can provide about 1 amp to each and occasional peak loads

to amps. otors typically controlled with this controller are near the si2e of a 03 mm

film plastic canister.

The -/4 has h$bridges on board, can handle 1amp and peak current draws to about0amps. 5ou often see motors between the si2e a of 03 mm film plastic canister and a

coke can, driven by this type #$%ridge. The -61477 has one h$bridge on board, can

handle about or 0 amps and can handle a peak of about 8 amps. This #$%ridge chip

can usually handle an average motor about the si2e of a coke. There are several more

commercially designed #$%ridge chips as well

WORKING OF CIRCUIT

This circuit drives small 6 motors up to about 177 watts or 3 amps or 97 volts,

whichever comes first. "sing bigger parts could make it more powerful. "sing a real #$

bridge I makes sense for this si2e of motor, but hobbyists love to do it themselves, and I

thought it was about time to show a tested

#$bridge motor driver that didn't use eotic parts.

peration is simple. otor power is re(uired, 8 to 97 volts 6. There are two logic level

compatible inputs, * and %, and two outputs, * and %. If input * is brought high, output *

goes high and output % goes low. The motor goes in one direction. If input % is driven,

the opposite happens and the motor runs in the opposite direction. If both inputs are low,the motor is not driven and can freely coast, and the circuit consumes no power. If both

inputs are brought high, the motor is shorted and braking occurs. This is a special feature

not common to most discrete #$bridge designs, drive both inputs in most

#$bridges and they self$destruct. *bout 7.73 amps is consumed in this state

To do &+ ;pulse width modulation< speed control, you need to provide &+ pulses.

&+ is applied to one input or the other based on direction desired, and the other inputis held either high ;=locked rotor>< or low ;=float>

Pe!"#$%&e'

&lease reference the accompanying schematic diagram. The circuit uses 6arlington

power transistors to reduce cost. @orward losses are typically 1 to volts, and since the

current must pass through two transistors, epect losses to total up to 9 volts at

maimum current. The 9 6arlington transistors need to be heat sink based on your

epected current and duty cycle.

&+ operation over 0 k#2 wills likely lead to high losses and more heat dissipation, due

to the simplicity of the circuit and the construction of 6arlington transistors. 5ou might get

away with higher fre(uencies if you put a 1A resistor emitter$base on each TI&1

transistor. I prefer to go with very low fre(uencies, 37 to 077#2.

Not shown in the schematic are the internal pinch$off resistors ;3A and 137 ohms< and

the damper diode that are built into all TI&1 series transistors. If you build your own

variation of the circuit with other parts, include these necessary parts. To the right is a

picture of the internals of the TI&1 transistors.

peration with logic signals greater than the motor supply voltage is allowed and

absorbed by B) and B4. The circuit is really intended to be operated with C logic

levels, logic high being about 9 volts.

If you live in the ".C., epect the TI&17 and TI&13 transistors to cost about D7.37 and

the very common and generic (uad$ &N* to cost about D7.17. *n inepensive

source for hobbyist$grade parts like these is Eameco Flectronics. *t low duty cycles,

currents up to the 4 amp rated peak of the transistors is allowed, but there is no current

limiting in this circuit, so it would be unwise to use this circuit to drive a motor that

consumes more than 3 amps when stalled.

N"(e) "% &*&+*( $))e#,-'

Transistors G1, , 0 and 9 must be heat sunk. Insulators should be used, or two separate

heat sinks isolated from each other and the rest of the world. Note that G1 and G0 are

grouped together and share common collectors and can share a heat sink. The same is

true for G and G9.

peration over 0 k#2 will lead to higher losses. If it is re(uired to run at higher fre(uency,

additional pinch$off resistors can be added to G1,,0 and 9, supplementing the internal

resistors. * good value would be 1k, and the resistors should be soldered from base to

emitter.

To reduce B@ emissions, keep the wires between the circuit and the motor short. No

freewheel diodes are re(uiredH they are internal to the TI& series 6arlington transistors.

6rive the circuit from 3$volt logic. 6rive levels higher than 3 volts will tend to heat up B1

and . This is A for short periods of time.

&ower supply voltage is 3 to 97 volts. utput current up to 3 amps is allowed if the power

supply voltage is 14 volts or less. &eak current must be kept below 4 amps at all times.

There is no current limiting in this circuit. Beversing a motor at full speed can cause it to

draw huge currents, understand your load to avoid damage. There are higher powered

devices in the TI& series of 6arlington transistorsH these can be substituted if needed.

-ook at the TI&197 and TI&193, please note they are in a bigger package and dont fitthe & board layout.

INSTRUCTION SETS

INSTRUCTION SET SUMMARY

Fach &I18JJ instruction is a 19$bit word divided into an &6F which specifies the

instruction type and one or more operands which further specify the operation of the

instruction. The &I18JJ instruction set summary in Table 10$ lists ,(e0"*e%(e, ,*(0"*e%(e, and -*(e$- $% &"%("- operations. Table 10$1 shows the opcode field

descriptions.

@or ,(e0"*e%(e instructions, f represents a file register designator and d represents

a destination designator.

The file register designator specifies which file register is to be used by the instruction.

The destination designator specifies where the result of the operation is to be placed. Ifd is 2ero, the result is placed in the + register. If d is one, the result is placed in the file

register specified in the instruction.

16


17/35

@or ,*(0"*e%(e instructions, b represents a bit field designator which selects the

number of the bit affected by the operation, while f represents the number of the file in

which the bit is located.

@or -*(e$- $% &"%("- operations, k represents an eight or eleven bit constant or literal

value.

TABLE 1201' OPCODE FIELD

DESCRIPTIONS

The instruction set is highly orthogonal and is grouped into three basic categories:

K B*(0"*e%(e operations

K L*(e$- $% &"%("- operations

*ll instructions are eecuted within one single instruction cycle, unless a conditional testis true or the program counter is changed as a result of an instruction.

In this case, the eecution takes two instruction cycles with the second cycle eecuted as

a N&. ne instruction cycle consists of four oscillator periods. Thus, for an oscillator

fre(uency of 9 #2, the normal instruction eecution time is 1 ms. If a conditional test is

true or the program counter is changed as a result of an instruction, the instruction

eecution time is ms. Table 10$ lists the instructions recogni2ed by the &*C

assembler.

@igure 10$1 shows the general formats that the instructions can have.

*ll eamples use the following format to represent a headecimal number:

7hh

where h signifies a headecimal digit.
