VND5E050MK-E Double-channel high-side driver with analog current sense for automotive applications

The VND5E050MJ-E and VND5E050MK-E are double-channel high-side drivers manufactured in the ST proprietary VIPower™ M0-5 technology and housed in the tiny PowerSSO-12 and PowerSSO-24 packages. The VND5E050MJ-E and VND5E050MK-E are designed to drive 12 V automotive grounded loads delivering protection, diagnostics and easy 3 V and 5 V CMOS compatible interface 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 in order to provide 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 allow sharing of the external sense resistor with other similar devices.
