描述 Description

The VN5E160ASO-E is a single channel high-side driver manufactured using ST proprietary VIPower?M0-5 technology and housed in SO-16L 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 withauto-restart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel providing ehnanced 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 the external sense resistor with similar devices.
