High-side switch minimises total power dissipation

Posted: 24 Aug 2009     Print Version  Bookmark and Share

Keywords:switch high-side  power dissipation  minimize power dissipation 

This technical article presents a single-chip quad high-side switch able to drive any type of load with one side connected to ground. The device�the VNI4140K�integrates on chip four low-voltage MOSFET channels (80 mΩ maximum RDS(on) at 25°C) with protection and diagnostic systems. The device is housed in the JEDEC standard PSSO-24 lead power package.

The VNI4140K uses STMicroelectronics' VI-Power technology; this is a proprietary smart-power technology that allows the integration on the same chip of both the control part and the power stage.

The VNI4140K is compliant with IEC 61131-2 (programmable logic controller international standard). Nevertheless, it can also be used as a smart-power solid-state relay in any other application with 36V maximum operating voltage.
