描述 Description

The VND5E050MCJ-E and VND5E050MCK-E are double channel high-side drivers manufactured using ST proprietary VIPower?M0-5 technology and housed in PowerSSO-12 and PowerSSO-24 packages. The devices are designed to drive 12 V automotive grounded loads, and to provide protection and diagnostics. They also implement a 3 V and 5 V CMOS-compatible interface for the use with any microcontroller.

The devices integrate 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 enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication and overtemperature indication.

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.
