VND5E050MJ-E VND5E050MK-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 V to 28 V CC PowerSSO-24 PowerSSO-12 Max on-state resistance(per ch.) R 50 m ON Electrostatic discharge protection Current limitation (typ) I 27 A LIMH (1) Off-state supply current I 2 A S Applications 1. Typical value with all loads connected. All types of resistive, inductive and capacitive loads General Suitable as LED driver Inrush current active management by power limitation Description Very low standby current The VND5E050MJ-E and VND5E050MK-E are 3.0 V CMOS compatible inputs double-channel high-side drivers manufactured in Optimized electromagnetic emissions the ST proprietary VIPower M0-5 technology Very low electromagnetic susceptibility and housed in the tiny PowerSSO-12 and In compliance with the 2002/95/EC PowerSSO-24 packages. The VND5E050MJ-E european directive and VND5E050MK-E are designed to drive 12 V Very low current sense leakage automotive grounded loads delivering protection, diagnostics and easy 3 V and 5 V CMOS Diagnostic functions compatible interface with any microcontroller. Proportional load current sense High-precision current sense for wide The devices integrate advanced protective currents range functions such as load current limitation, inrush and overload active management by power Current sense disable limitation, overtemperature shut-off with Overload and short to ground (power auto-restart and overvoltage active clamp. A limitation) indication dedicated analog current sense pin is associated Thermal shutdown indication with every output channel in order to provide Protections enhanced diagnostic functions including fast Undervoltage shutdown 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 The current sensing and diagnostic feedback of the whole device can be disabled by pulling the Protection against loss of ground and loss CS DIS pin high to allow sharing of the external of V CC sense resistor with other similar devices.
