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. 

ST’s M0-7 “Enhanced” (M0-7E) High-Side Drivers enrich the existing M0-7 family with 5 brand-new devices featuring extremely high current sensing precision and ultra-low voltage capability during the car cold cranking phase. Derived from ST’s proprietary VIPower® technology, these fully protected M0-7E high-side switches have a RDS(ON) ranging from 10 to 100 mOhm, one to four channels, and are hosted in the tiny PowerSSO-16 package with full pin-to-pin compatibility.
