AOZ1321DI Load Switch with Controlled Slew Rate General Description The AOZ1321DI is a P-channel high-side load switch with controlled slew rate. Three slew rate options are available. The AOZ1321DI-01L and AOZ1321DI-04L have slew rates of 800us. The AOZ1321DI-02L and AOZ1321DI -05L feature fast Slew Rate (less than 1µs). The slew rate of AOZ1321DI-03L and AOZ1321DI-06L is 100µs. The AOZ1321DI-03L, AOZ1321DI-04L, and AOZ1321DI-05L provide an output discharge circuit to quickly discharge the output when the switch is disabled. The P-channel MOSFET has typical on resistance of 60mΩ. The very low RDS(ON) significantly reduces the power path dissipation. The input voltage range of AOZ1321DI is from 1.6V to 5.5V. The control input is compatible with both TTL and CMOS logic.
