The BQ24740 is a high-efficiency, synchronous battery charger IC with integrated loop compensation and system power selector logic, making it ideal for space-constrained, multi-chemistry battery charging applications such as laptops. It offers accurate adapter current sensing (±3%) and input current sensing (±2%), with internal soft-start and safety features like input overvoltage protection (OVP) and reverse conduction protection. Charging parameters, including charge voltage (4–4.512V per cell) and charge current (up to 10A), can be programmed either via resistors or by a system microcontroller using DACs or GPIOs.
