AiT Semiconductor Inc. www.ait-ic.com A4770 POWER SWITCH 100mΩ POWER DISTRIBUTION SWITCHES DESCRIPTION FEATURES The A4770 is an integrated 100mΩ power switch for self-powered and bus-powered Universal Series Bus (USB) applications. A built-in charge pump is used to drive the N-channel NMOSFET that is free of parasitic body diode to eliminate any reversed current flow across the switch when it is powered off. Its low quiescent supply current (23μA) and small package (SOT-25) is particularly suitable in battery-powered portable equipment.  100mΩ (Typ.) High-Side NMOSFET (SOT-25)  1.1/1.3A Current Limit  Small SOT-25 Package Minimizes Board Space  Soft Start  Thermal Protection  Low 23μA Supply Current  Wide Input Voltage Range: 2.
