VND5E050ACJ-E VND5E050ACK-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 PowerSSO-24 PowerSSO-12 Max On-state resistance (per ch.) R 50 m ON Reverse battery protected Current limitation (typ) I 27 A LIMH Electrostatic discharge protection (1) Off-state supply current I 2 A S 1. Typical value with all loads connected. Applications General All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Suitable as LED driver Very low standby current 3.0 V CMOS compatible inputs Description Optimized electromagnetic emissions Very low electromagnetic susceptibility The VND5E050ACJ-E and VND5E050ACK-E are double channel high-side drivers manufactured Compliance with European directive using ST proprietary VIPower M0-5 technology 2002/95/EC and housed in PowerSSO-12 and PowerSSO-24 Very low current sense leakage packages. The devices are designed to drive 12 V Diagnostic functions automotive grounded loads, and to provide Proportional load current sense protection and diagnostics. They also implement High current sense precision for wide a 3 V and 5 V CMOS-compatible interface for use currents range with any microcontroller. Current sense disable The devices integrate advanced protective Off-state open load detection functions such as load current limitation, inrush Output short to V detection and overload active management by power CC 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 providing enhanced Protections diagnostic functions including fast detection of Undervoltage shutdown overload and short-circuit to ground through Overvoltage clamp power limitation indication, overtemperature indication, short-circuit to V diagnosis on-state Load current limitation CC and off-state open-load detection. Self limiting of fast thermal transients Protection against loss of ground and loss The current sensing and diagnostic feedback of of V the whole device can be disabled by pulling the CC CS DIS pin high to share the external sense Overtemperature shutdown with auto resistor with similar devices. restart (thermal shutdown) September 2013 Doc ID 022515 Rev 2 1/43 www.st.com 1 Contents VND5E050ACJ-E, VND5E050ACK-E Contents 1 Block diagram and pin description . 6 2 Electrical specifications 8 2.1 Absolute maximum ratings . 8 2.2 Thermal data . 9 2.3 Electrical characteristics . 9 2.4 Waveforms 18 2.5 Electrical characteristics curves 21 3 Application information . 24 3.1 GND protection network against reverse battery . 24 3.1.1 Solution 1: resistor in the ground line (RGND only) 24 3.1.2 Solution 2: diode (DGND) in the ground line . 25 3.2 Load dump protection 25 3.3 MCU I/Os protection . 25 3.4 Current sense and diagnostic 25 3.4.1 Short to VCC and off-state open-load detection 26 3.5 Maximum demagnetization energy (VCC = 13.5V) . 28 4 Package and PCB thermal data . 29 4.1 PowerSSO-12 thermal data . 29 4.2 PowerSSO-24 thermal data . 31 5 Package and packing information . 35 5.1 ECOPACK . 35 5.2 PowerSSO-12 package information . 35 5.3 PowerSSO-24 package information . 37 5.4 PowerSSO-12 packing information . 39 5.5 PowerSSO-24 packing information . 40 6 Order codes . 41 7 Revision history . 42 2/43 Doc ID 022515 Rev 2
