Cxus7703cb is a power switch circuit with only 100m Ω on internal resistance and applied to USB power supply. The built-in charge pump boosts the voltage to drive the NMOS power transistor. When it is in the off state, the reverse conduction current of the switch is eliminated by the parasitic reverse body diode. Low static power consumption (23 μ a) and small package (sot-23-5) are especially suitable for battery powered portable devices. Protection circuit includes soft start circuit to prevent inrush current during power on, 1.1a overcurrent protection circuit is necessary for USB power supply, with built-in thermal shutdown protection circuit and short circuit protection circuit
