ST replaces car relays with tiny switch IC
STMicroelectronics has introduced high-side switch ICs which can be use to replace conventional relays for vehicle electronics such as lights and body modules.
The switches are available in a common package style so that modules suppliers can build several variants using the same basic hardware and software so car makers can address differing requirements in international markets and offer various model specifications.
The latest VIPower switch products, the M0-7 series are available in a 5 x 4mm package.
Changes to the internal design increase precision, improve diagnostic feedback and reliability.
Specifically, there is greater protection against short circuits, more accurate voltage and temperature feedback, increased current-sense precision, and best-in-class electromagnetic emission (EMI) performance.
Samples of all family members are available now
The first device to enter production will be the dual-channel VND7020AJ-E, in Q2.
The full range of package types available across the new family will include PowerSSO-16, PowerSSO-36, Octapak, and SO-8.Tags: chips, relays, ST
