APL3538

APL3538 Preliminary Ultra-Low On-Resistance, 6A Dual Load Switch with Soft Start Features Ultra-Low On-Resistance -APL3538A/B: 20mΩ (Max.) -APL3538C/D: 35mΩ (Max.) Low Quiescent Current: 30µA(max) Soft Start Time Programmable by External Capacitor Wide Input Voltage Range (VIN): 0.8V to 5.5V Supply Voltage Range (VDD): 3V to 5.5V Over-Current Protection (OCP) Enable Control Function Output Discharge when Switch Disabled Reverse Current Blocking when Switch Disabled Over-Temperature Protection with Hysteresis Tiny small TQFN2x2-14 Package Lead Free and Green Devices Available (RoHS Compliant) Gereral Description The APL3538 is an ultra-low On-resistance, dual powerdistribution switch with external soft start control. It integrates two N-channel MOSFETs that can deliver 6A continuous load current each. The APL3538 can be enabled by other power systems. Pulling and holding the voltage of EN pin (APL3538A) below 0.4V shuts off the output. Pulling and holding the voltage of ENB pin (APL3538B) below 0.4V enable the output. The device integrates some protection features, including Over-Current Protection (OCP) and Over-Temperature Protection (OTP). The OCP can protect the device against current over-loads or shortcircuit events. The OTP function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 150°C and will automatically turns on the power switch when the temperature drops by 30°C. The device is available in lead fre...
