BQ51013ARHLR Description
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:
- Multichemistry support: Compatible with lithium-ion, lithium-polymer, lithium-iron-phosphate (LiFePO4), lead-acid, and nickel-metal hydride (NiMH) batteries.
- Wide input voltage range: Operates with input voltages from 3.5V to 24V.
- High output current: Can deliver up to 5A output current to the battery.
- High efficiency: The integrated buck converter and charging circuitry provide high efficiency for improved power management.
- Battery protection: Includes overcharge, over-discharge, over-current, and short-circuit protection.
- Charge termination: Supports constant current/constant voltage (CC/CV) charging and provides charge termination based on battery voltage and current.
- I2C communication: Allows for easy configuration and monitoring of the charging process through an I2C interface.
- Thermal management: Features thermal shutdown and thermal regulation to protect the device and battery from overheating.
- Small form factor: Available in a compact 40-pin, 7mm x 7mm QFN package.
Applications:
