BQ24005PWPR Datasheet PDF - TI

DESCRIPTION

●The bq2400x series ICs are advanced Li-Ion linear charge management devices for highly integrated and space-limited applications. They combine high accuracy current and voltage regulation; FET pass transistor and reverse-blocking Schottky; battery conditioning, temperature, or input-power monitoring; charge termination; charge-status indication; and charge timer in a small package.

●FEATURES
