Product overview
Description
The VNQ5E050AK-E is a quad channel high-side driver manufactured using ST proprietary VIPower™ M0-5 technology and housed in PowerSSO-24 package. The device is designed to drive 12 V automotive grounded loads, and to provide protection and diagnostics. It also implements a 3 V and 5 V CMOS compatible interface for the use with any microcontroller.
The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto-restart and overvoltage active clamp.
A dedicated analog current sense pin is associated with every output channel providing enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to VCCdiagnosis and on-state and off-state open-load detection. The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to share external sense resistor with similar devices.
