Over-Temperature Protection

The APL3533 is an ultra-low on-resistance, dual power-

distribution switch with external soft start control. It inte-

grates two N-channel MOSFETs that can deliver 6A con-

tinuous load current each.

The device integrates over-temperature protection. The

over temperature protection function shuts down the N-

channel MOSFET power switch when the junction tem-

The device is available in lead free TDFN2x3-14A
