bq2954 Datasheet Lithium-Ion Charge

Manufacturer: Texas Instruments

Datasheet Details

The bq2954 Li-Ion Charge-Management IC uses a flexible pulse-width modulation regulator to control voltage and current during charging.

The regulator frequency is set by an external capacitor for design flexibility.

The switch-mode design minimizes power dissipation.

bq2954 Lithium Ion Charge Management IC with Integrated Switching.

Safe charge of Li-Ion battery packs.
Pulse-width modulation control for current and voltage regulation.
Programmable high-side/low-side current-sense.
Fast charge terminated by selectable minimum current; safety backup termination at maximum time.
Pre-charge qualification detects shorted or damaged cells and conditions battery.
Charging continuously qualified by temperature and voltage limits.
Direct LED control outputs to display c.
