Зарядные ИС для аккумуляторов BQ24765RUVT

Зарядное устройство для универсальной 4-элементной батареи , 24В вход, 4А зарядка, VQFN-34

The BQ24765RUVT is a high-efficiency synchronous Battery Charger with two integrated 30mR NMOS power MOSFETs and an integrated input current comparator, offering low component count for space-constraint, multi-chemistry battery charging applications. Input current, charge current and charge voltage DACs allow for very high regulation accuracies that can be easily programmed by the system power management micro-controller using SMBus. It has switching frequency of 700kHz. It features dynamic power management (DPM) and input power limiting. These features reduce battery charge current when the input power limit is reached to avoid overloading the AC adaptor when supplying the load and the battery charger simultaneously. A high-accuracy current sense amplifier enables accurate measurement of input current from the AC adapter, allowing monitoring the overall system power.
