ST VND5E050ACKTR-E

The VND5E050ACJ-E and VND5E050ACK-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 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 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 VCC diagnosis 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.
