BQ24741RHDR Description

Short technical summary and product information.

The BQ24741RHDR from Texas Instruments is a high-efficiency, synchronous buck converter battery charger IC. It is designed for space-constrained Li-ion or Li-polymer battery charging applications, offering integrated compensation and a low component count.

 

This charger supports two to four series Li+ cells, capable of delivering up to 10A of charge current. It operates within a 9V to 24V input voltage range and features ratiometric charge voltage and current programming for high regulation accuracy. The device includes essential safety protections such as over-current, over-temperature, over-voltage, and short-circuit protection.

 

Packaged in a 28-pin VQFN (5x5mm) with an exposed pad, the BQ24741RHDR is suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ), making it robust for various environmental conditions. Key features include a trickle-charge current of 150mA and low quiescent current in off-state.

 

Applications for the BQ24741RHDR include notebook computers, ultra-mobile PCs, portable data capture terminals, portable printers, medical diagnostics equipment, battery bay chargers, and battery back-up systems.
