VN5E025AJTR-E

The VN5E025AJ-E is a single channel high-side driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny PowerSSO-12 package. The VN5E025AJ-E is designed to drive 12 V automotive grounded loads delivering protection, diagnostics and easy 3V 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, over-temperature shut-off with autorestart 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, over-temperature indication, short-circuit to VCC diagnosis and ONstate 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 allow sharing of the external sense resistor with other similar devices
