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. The ITS4040D-EP-D is specifically designed to switch resistive, inductive or capacitive loads in harsh industrial environments. The ITS4040D-EP-D is equipped with essential protection features that make it extremely robust. Diagnostic information can be read out via the STATUS output (ST). The two channel device can be controlled with two separate input pins. Due to their high voltage capability the input pins can be directly interfaced to optocouplers without additional external components.
