DESCRIPTION

JW®3633 is power management solution for

portable battery charger system.

The device contains a full-featured battery

charger with up to 2A charge current, a 2.4A

output and battery protection functions.

Charge mode: The charger can be powered from

5V wall adaptor with ±10% variation whereas over

voltage lock out protects internal circuit during

voltage surge.

The device automatically turns-off charging and

bypassing function when input voltage exceeds

6.1V, and can sustain up to 10V continuous input

voltage with charging and bypassing function in

OFF status.

The device has a preset battery float voltage of

4.2V/4.35V programmable by external resistor

with ±1% accuracy at room temperature. The

integrated charger minimizes the charger’s

physical footprint, maximizes charge efficiency,

which reduces the power dissipation during

charge.

Discharge mode: The system power the output

with 2.4A capacity.

In both charge and discharge mode, PFM is

engaged to maintain high efficiency at light load.

JW3633 guarantee robustness with short-circuit

protection, thermal protection, and input under

and over voltage lockout.

They are available in a 24-pin QFN4X4 package

with exposed pad for low thermal resistance.
