bq2954 Features

* ➤ 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 da

bq2954 General Description

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 .
