The ITS4040D-EP-D is a 40mΩ Dual Channel Smart High-Side Power Switch providing integrated protection functions and a diagnosis feedback. With two channels capable of currents of more than 2 A each, very low typical RDS(ON) values of 60 mΩ at Tj = 125°C and the small PG-TSDSO-14 exposed pad package it combines high current capability with minimum space requirements. The exposed pad of the thermally enhanced PG-TSDSO-14 package allows a very efficient heat transfer from the device to inner layers of the PCB by means of thermal vias. The power transistors are built by N-channel vertical power MOSFETs (DMOS) with charge pump.
