VND5E025BK-E Double channel high-side driver with analog current sense for automotive applications Features Max transient supply voltage VCC 41 V Operating voltage range VCC 4.5 to 28 V Max on-state resistance (per ch.) RON 25 mΩ Current limitation (typ) ILIMH 60 A Off-state supply current IS 2 µA(1) PowerSSO-24 ■ All types of resistive, inductive and capacitive loads and suitable as LED driver 1. Typical value with all loads connected. Description ■ General – Inrush current active management by power limitation – Very low standby current – 3.0V CMOS compatible inputs ■ Diagnostic functions – High current sense precision for wide currents range – Current sense ratio drift for single point calibration – Current sense disable – Overload and short to ground (power limitation) indication – Thermal shutdown indication ■ Protections – Undervoltage shutdown – Overvoltage clamp – Load current limitation – Self limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Overtemperature shutdown with auto restart (thermal shutdown) – Reverse battery protected – Electrostatic discharge protection Applications ■ The VND5E025BK-E is a double channel highside 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 "doublepoint" 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.
