Description
The VND5E025LK-E is a double channel highside drivers manufactured in the ST proprietary VIPower M0-5 technology and housed in the tiny PowerSSO-24 package. The VND5E025LK-E is designed to drive 12V automotive grounded loads delivering protection, diagnostics and easy 3V and 5V 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 auto-restart and over-voltage active clamp. A dedicated analog current sense pin is associated with every output channel in order to provide Ehnanced 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. Max transient supply voltage VCC 41 V Operating voltage range VCC 4.5 to 28 V Max On-state resistance (per ch.) RON 25 m Current limitation (typ) ILIMH 42 A Off state supply current IS 2 µA(1) 1. Typical value with all loads connected. PowerSSO-24
