ADP5350ACPZ-1-R7

ADP5350 is a power management IC (PMIC), combines one high performance buck regulator for single Li-Ion/Li-Ion polymer battery charging, a fuel gauge, a highly programmable boost regulator for LED backlight illumination, and three 150 mA LDO regulators. It operates in trickle charge mode and in constant current (CC) and constant voltage (CV) fast charge mode. It features an internal field effect transistor (FET) that permits battery isolation on the system power side. The device's fuel gauge is a space-saving and low current consuming solution. It is optimal for rechargeable Li-Ion battery powered devices, and features a voltage-based, battery SOC measurement function. The device's boost regulator operates at a 1.5MHz switching frequency. It is used in application such as rechargeable Li-ion and Li-ion polymer battery-powered devices, portable consumer devices, portable medical devices, portable instrumentation devices, wearable devices etc.
