SC804A - Fully Integrated 4.4V Lithium-Ion Battery Charger System

Datasheet Summary

Description

The SC804A is a fully integrated full-feature, single cell constant-current/constant-voltage (CC/CV) 4.4V LithiumIon battery charger.

With an integrated timer and complete charge control algorithm, the SC804A is ideal for stand-alone charger applications.

Features

Fully integrated charger with FET pass transistor, reverse-blocking diode, sense resistor, timer, and thermal protection Battery voltage controlled to 1% accuracy Programmable precharge, fastcharge & termination current over wide range, with analog current control reference input for design ﬂexibility Up to 1.5A continuous charge current Input voltage range from 3V to 14V Soft-start reduces start-of-charge adapter load transients NTC thermistor sense input and adjustable cold temperature thresho.

Fully Integrated 4.4V Lithium-Ion www.DataSheet4U.com Battery Charger System with Timer POWER MANAGEMENT Description The SC804A is a fully integrated full-feature, single cell constant-current/constant-voltage (CC/CV) 4.4V LithiumIon battery charger. With an integrated timer and complete charge control algorithm, the SC804A is ideal for stand-alone charger applications. The SC804A contains programmable pre-charge, fast-charge and termination current settings. The SC804A can be programmed to terminate charging based on the output current or the time-out of the programmable timer. The fast charge current is typically set with an external resistor, but it can also be adjusted by applying an analog voltage to the AFC pin.
