Next-generation VIPower M0-7 intelligent high-side switches

ST's new family of VIPower M0-7 intelligent power switches provide enhanced intelligent features, improve protection and reliability, and are up to 40% smaller than competing alternatives. Pioneered by ST, intelligent high-side switches provide a more reliable and efficient replacement for conventional relays.

The VIPower family has offered advantages such as a common package style for many devices in the range. This allows tier-one suppliers to build several module variants using the same basic hardware and software so car makers can address differing requirements in international markets and offer various model specifications and options cost-effectively. The common-package approach has become widely adopted among high-side switch vendors.

In the VIPower M0-7 series, 75% of family members are available in a 5 x 4 mm package, which is 40% smaller than the smallest competing devices. This allows car electronics designers to save pc-board space and aim for smaller module sizes. Moreover, various internal design changes increase precision, enhance diagnostic feedback, and improve reliability.

Specifically, performance improvements include greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
