BQ24304 Datasheet Protection Ic

Manufacturer: Texas Instruments

Overview: www.ti.com bq24300 bq24304 bq24305 SLUS764C – AUGUST 2007 – REVISED DECEMBER 2009 OVERVOLTAGE AND OVERCURRENT PROTECTION IC AND Li+ CHARGER FRONT-END PROTECTION IC Check for Samples: bq24300 bq24304.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The bq24300 and bq24304 are highly integrated circuits designed to provide protection to Li-ion batteries from failures of the charging circuit.

The IC continuously monitors the input voltage, the input current, and the battery voltage.

The device operates like a linear regulator: for voltages up to the Input Overvoltage threshold, the output is held at 5.5V (bq24300), 5.0V (bq24305) or 4.5V (bq24304).
