BQ24725ARGRT Descrizione generale

The BQ24725ARGRT is designed to meet the demands of space-constrained, multi-chemistry battery charging applications. With its high-efficiency and low component count, this synchronous battery charger offers a reliable solution for charging one, two, three, or four series Li+ cells. The use of two charge pumps allows for separate control of n-channel MOSFETs, enabling automatic system power source selection. Additionally, the SMBus controlled input current, charge current, and charge voltage DACs provide the flexibility for high regulation accuracies, easily programmable by the system power management micro-controller. Whether using the internal input current register or the external ILIM pin, the BQ24725ARGRT is equipped to throttle down PWM modulation for reduced charge current, ensuring efficient and controlled charging
