High-side switches can safely drive high currents into complex (resistive, inductive and capacitive) grounded loads in compliance with the harsh automotive environment. This requires both a robust, low on-resistance power switch and accurate analog circuitry for diagnostic, protection and control functions.

ST’s VIPower® family consists of a set of automotive-qualified high-side switches covering the full load range in terms of type and rated power and includes state-of-the-art embedded control functions and a brand-new protection mechanism. This offer represents the ideal solution for car systems such as junction boxes, interior/exterior lighting and DC motor driving as well as every application inside and outside the transportation domain requiring a protected 12V battery line. 

VIPower Zero series drive Automotive Heating Systems

ST’s VIPower® Zero series offers innovative and high-performance protected switches for driving high-power loads.

This series covers today’s growing demand for intelligent high-side switches able to drive and protect high-power loads such as automotive heating systems including seat-heating, window defroster, cabin and steering heaters.

In addition to outstanding thermal performances in tiny and eco-friendly packages, this series is perfect for Start & Stop systems and other applications required to work at very low battery voltages (device option).

The VIPower Zero series is also suitable for high-current fan motors and protected battery lines in electrical power distribution systems.
