Overview
The VNQ7050AJ-E is a quad-channel high-side driver manufactured by STMicroelectronics using their proprietary VIPower M0-7 technology. This device is housed in a PowerSSO-16 package and is designed to drive 12 V automotive grounded loads through a 3 V and 5 V CMOS-compatible interface. It integrates advanced protective functions such as load current limitation, overload active management by power limitation, and overtemperature shutdown with configurable latch-off. The device also features a FaultRST pin to unlatch the output in case of a fault and a sense enable pin for OFF-state diagnosis and external sense resistor sharing among similar devices.
