Awinic AW33905FCR is an innovative power distribution switch with PMIC (Power Management Integrated Circuit) technology. It is designed in a 9-pin FCQFN (Flip Chip Quad Flat No-Lead) package, 1.2x1.2 mm in size, and is RoHS-compliant for hazardous substance and environmental protection.This tiny switch device offers 3 power input rails with voltage range of 2.7V-5.5V and a maximum output current of 40mA per rail. It integrates 4 dedicated power switches for multi-level on/off control. The AW33905FCR ensures up to 96% power efficiency in the on-state, and up to 99% power efficiency in the off-state. Furthermore, the device has an over-temperature protection (OTP) and various built-in protection features like over-voltage protection (OVP), under-voltage lockout (UVLO), thermal shutdown (TSD), surge protection (SP), and external short-circuit protection (ESCP).Overall, Awinic AW33905FCR is an ideal solution for power management in battery powered remote electronic devices.
