BQ51013ARHLR

The BQ51013ARHLR is a highly integrated, multichemistry battery charge controller from Texas Instruments (TI). It is designed to provide a complete charging solution for single-cell lithium-ion, lithium-polymer, and lithium-iron-phosphate (LiFePO4) batteries, as well as lead-acid and nickel-metal hydride (NiMH) chemistries.

Description:

The BQ51013ARHLR is a system-in-package (SiP) device that integrates a high-efficiency, step-down (buck) converter with a high-voltage, high-current battery charger. It features a wide input voltage range (from 3.5V to 24V) and is capable of delivering up to 5A output current to the battery. The device is available in a compact 40-pin, 7mm x 7mm QFN package.

Features:

1. Multichemistry support: Compatible with lithium-ion, lithium-polymer, lithium-iron-phosphate (LiFePO4), lead-acid, and nickel-metal hydride (NiMH) batteries.
2. Wide input voltage range: Operates with input voltages from 3.5V to 24V.
3. High output current: Can deliver up to 5A output current to the battery.
4. High efficiency: The integrated buck converter and charging circuitry provide high efficiency for improved power management.
5. Battery protection: Includes overcharge, over-discharge, over-current, and short-circuit protection.
