BQ24130 Datasheet Battery/supercapacitor Charger

Manufacturer: Texas Instruments

Overview: bq24130 www.ti.com SLUSAN2C – JULY 2011 – REVISED JUNE 2012 600-kHz Synchronous Switch-Mode Host-Controlled Battery/Supercapacitor Charger With 4-A Integrated MOSFETs Check for Samples:.

General Description

The bq24130 is an integrated host-controlled Li-ion and Li-polymer switch-mode battery charge controllers with two integrated N-channel power MOSFETs.

It offers a constant-frequency synchronous PWM controller with high accuracy regulation of charge current and voltage.

The fast charge and precharge current can be either hardwired with resistors or programmed by system power management microcontroller using a DAC or GPIOs.
