VND5E025MK-E Double-channel high-side driver with analog current sense for automotive applications Features Max transient supply voltage V 41 V CC Operating voltage range V 4.5 to 28 V CC Max on-state resistance (per ch.) R 25 m ON PowerSSO-24 Current limitation (typ) I 60 A LIMH Reverse battery protected (see Figure 29: (1) Off-state supply current I 2A S (1) Application schematic ) 1. Typical value with all loads connected. Electrostatic discharge protection Applications General Inrush current active management by All types of resistive, inductive and capacitive power limitation loads Very low standby current Suitable as LED driver 3.0V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility The VND5E025MK-E is a double-channel high- In compliance with the 2002/95/EC side drivers manufactured in the ST proprietary european directive VIPower M0-5 technology and housed in the Very low current sense leakage tiny PowerSSO-24 package. Diagnostic functions The VND5E025MK-E is designed to drive 12V Proportional load current sense automotive grounded loads delivering protection, High current sense precision for wide diagnostics and easy 3V and 5V CMOS currents range compatible interface with any microcontroller. Current sense disable The device integrates advanced protective Overload and short to ground (power functions such as load current limitation, inrush limitation) indication and overload active management by power Thermal shutdown indication limitation, overtemperature shut-off with auto-restart and overvoltage active clamp. Protections Undervoltage shutdown A dedicated analog current sense pin is associated with every output channel in order to Overvoltage clamp provide Enhanced diagnostic functions including Load current limitation fast detection of overload and short-circuit to Self limiting of fast thermal transients ground through power limitation indication and Protection against loss of ground and loss overtemperature indication. of V CC The current sensing and diagnostic feedback of Overtemperature shutdown with auto the whole device can be disabled by pulling the restart (thermal shutdown) CS DIS pin high to allow sharing of the external sense resistor with other similar devices.
