The SY5702 is an ultra-low quiescent current (IQ: 250nA, ISD: 10nA) load switch with reverse current protection and high switching speed. It integrates a 42mΩ (typ.) N-channel MOSFET, which can work with input voltage range of 1.2V to 5.5V and load 2A continuous current.
The EN pin leakage current is only 5nA due to the smart pull-down resistor. It supports the 1.2V I/O application. The EN pin has an internal 1MΩ pull-down resistor that allows to float this pin. In order to reduce leakage current, the resistor will be disconnected when the voltage of EN pin is higher than VIH.
The SY5702 integrates output slew rate control to avoid inrush current while controlling short turn-on time. The typical turn-on time of switch is 100μS. The SY5702 is available in FOCSP-0.76mm x 0.76mm-4B and DFN-1mm x 1mm-4L package.
