Infineon ITS4090QEPDXUMA1, QuadHigh Side, High Side Power Switch IC 14-Pin, PG-TSDSO-14

The ITS4090Q-EP-D is a 90mΩ Quad Channel Smart High-Side Power Switch providing integrated protection functions and a diagnosis feedback. With four channels capable of currents of more than 500 mA each, very low typical RDS(ON) values of 140mΩ at Tj = 125°C and the small PG-TSDSO-14 exposed pad package it combines high flexibility 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 ITS4090Q-EP-D is specifically designed to switch resistive, inductive or capacitive loads in harsh industrial environments. The ITS4090Q-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 four channel device can be controlled with four separate input pins. Due to their high voltage capability the input pins can be directly interfaced to optocouplers without additional external components.
