EV-VND5E160AJ provides you an easy way to connect ST’s surface mounted VIPower®drivers into your existing prototype circuitry. This evaluation board comes pre-assembled with VND5E160AJ-E high-side driver.
The VND5E160AJ-E is a double channel high-side driver manufactured using ST proprietary VIPower M0-5 technology and housed in PowerSSO-12 package. The VND5E160AJ-E is designed to drive 12V automotive grounded loads, providing protection, diagnostics and easy 3 V and 5 V CMOS-compatible interface 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 with auto-restart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel provides enhanced 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.
