High-Efficiency Charger for Li-Ion Batteries

The ZSPM4551 is a DC/DC synchronous switching lithium-ion (Li-Ion) battery charger with fully integrated power switches, internal compensation, and full fault protection. Its switching frequency of 1MHz enables the use of small filter components, resulting in smaller board space and reduced BOM cost VBAT reverse-current blocking\nProgrammable temperature-compensated termination voltage: 3.94V to 4.18V ±1%\nUser programmable maximum charge current: 50mA to 1500mA\nCurrent mode PWM control in constant voltage\nSupervisor for VBAT reported at the NFLT pin\nInput supply under-voltage lockout\nF;
