bq24705 Datasheet Host-controlled Multi-cell Battery Charger

Manufacturer: Texas Instruments

Overview: Not Recommended for New Designs bq24705 www.ti.com...............................................................................................................................................

General Description

The bq24705 is a high-efficiency, synchronous battery charger with integrated compensation, offering low component count for space-limited multi-chemistry battery charging applications.

Charge current and voltage programming allows high regulation accuracies, and can be either hardwired with resistors, or programmed by the system power-management microcontroller using a DAC
