Typical value with all loads connected. Description General The VND5E025BK-E is a double channel high- Inrush current active management by side driver manufactured in the ST proprietary power limitation VIPower M0-5 technology and housed in the tiny PowerSSO-24 package. The VND5E025BK-E Very low standby current is designed to drive 12V automotive grounded 3.0V CMOS compatible inputs loads delivering protection, diagnostics and easy Diagnostic functions 3V and 5V CMOS compatible interface with any High current sense precision for wide microcontroller. currents range The device integrates advanced protective Current sense ratio drift for single point functions such as load current limitation, inrush calibration and overload active management by power Current sense disable limitation, overtemperature shut-off with auto Overload and short to ground (power restart and overvoltage active clamp. limitation) indication A dedicated analog current sense pin is Thermal shutdown indication associated with every output channel in order to Protections provide Enhanced diagnostic functions including Undervoltage shutdown fast detection of overload and short circuit to ground through power limitation indication and Overvoltage clamp overtemperature indication. Load current limitation Self limiting of fast thermal transients An improved current sense circuitry and the introduction of a new current sense ratio drift, Protection against loss of ground and loss dK/K(tot), allow thesingle-poin calibration and of V CC ensure a very high accuracy in case ofdouble- Overtemperature shutdown with auto poin calibration. restart (thermal shutdown) Reverse battery protected The current sensing and diagnostic feedback of the whole device can be disabled by pulling the Electrostatic discharge protection CS DIS pin high to allow sharing of the external sense resistor with other similar devices.
