The VND5E025BK-E is a double channel high-side driver manufactured in the ST proprietary VIPower™ M0-5 technology and housed in the tiny PowerSSO-24 package. The VND5E025BK-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, 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.
An improved current sense circuitry and the introduction of a new current sense ratio drift, dK/K(tot), allow the "single-point" calibration and ensure a very high accuracy in case of "double-point" calibration.
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.
