Overview
The VND7050AJTR-E, produced by STMicroelectronics, is a double-channel high-side driver designed for automotive applications. This device is manufactured using ST's proprietary VIPower® M0-7 technology and is housed in a PowerSSO-16 package. It is engineered to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface, providing advanced protection and diagnostic functions.
The VND7050AJTR-E features very low standby current, compatibility with 3 V and 5 V CMOS outputs, and integrates multiple protective functions such as load current limitation, overload active management, and overtemperature shutdown with configurable latch-off. The device also includes a multifunction multiplexed analog output pin for sophisticated diagnostic functions.
