BQ24751ARHDR Description

Short technical summary and product information.

The Texas Instruments BQ24751ARHDR is a high-efficiency, synchronous NMOS-NMOS buck battery charger with integrated system power selector logic. It is designed for space-constrained multi-chemistry battery charging applications in notebooks, portable terminals, and medical diagnostics equipment.

 

The charger supports 2, 3, or 4 series Li+ cells and can deliver up to 10A of charge current. It operates from a 5V to 24V AC/DC adapter input and features ratiometric programming of charge voltage (4-4.512 V/cell) and charge current via resistors or DAC/GPIO. The device includes programmable input overvoltage protection (OVP), dynamic power management (DPM), and inrush adapter power limiting (ACOP).

 

The BQ24751ARHDR is offered in a 28-pin VQFN (5x5 mm) package with an exposed pad for thermal management. It operates over a temperature range of -40°C to 125°C and is suitable for a wide range of portable and battery-powered applications.
