VIPower M0-5 H-bridges - hardware design guide
Introduction
Understanding the behavior of the latest generation VIPower H-bridges for DC motor control in
automotive applications can facilitate design and reduce costs.
The M0-5 generation of drivers builds on the knowledge derived from previous generations, with
improved robustness functionality and package density. The integration of high side driver (HSD) switch
chips and low side driver (LSD) chips in the one package (hybrid approach) pin allows minimization, a
reduced component count, improved reliability and the saving of board space.
The combination of logic functions with analog power structures in the silicon allows an intelligence
inside the chip which goes beyond simple driving to protection and fault feedback to a microcontroller
across wide temperature and battery voltage ranges.
