bq2954 Datasheet (Texas Instruments)

bq2954, Lithium-Ion Charge

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.

For safety, the bq2954 inhibits
