Description
The VND5E050AJ-E and VND5E050AK-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 VND5E050AJ-E and VND5E050AK-E are designed to drive 12V automotive grounded loads delivering protection, diagnostics and easy 3V and 5V 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, over-temperature shut-off with auto-restart and over-voltage 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, overtemperature indication, short-circuit to Vcc diagnosis and on & 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 allow sharing of the external sense resistor with other similar devices.
