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 VND5E050AJ-E and VND5E050AK-E are double channel high-side drivers manufactured in In compliance with the 2002/95/EC the ST proprietary VIPower M0-5 technology and european directive housed in the tiny PowerSSO-12 and PowerSSO- Very low current sense leakage 24 packages. The VND5E050AJ-E and Diagnostic functions VND5E050AK-E are 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 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, over-temperature shut-off with Overload and short to ground (power auto-restart and over-voltage 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 Overvoltage clamp through power limitation indication, over- temperature indication, short-circuit to Vcc Load current limitation diagnosis and on & 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 allow sharing of the external Over temperature shutdown with auto sense resistor with other similar devices. restart (thermal shutdown) September 2013 Doc ID 14617 Rev 5 1/44 www.st.com 1 Contents VND5E050AJ-E / VND5E050AK-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 19 2.5 Electrical characteristics curves 22 3 Application information . 25 3.1 GND protection network against reverse battery . 25 3.1.1 Solution 1: resistor in the ground line (RGND only) 25 3.1.2 Solution 2: diode (DGND) in the ground line . 26 3.2 Load dump protection 26 3.3 MCU I/Os protection . 26 3.4 Current sense and diagnostic 26 3.4.1 Short to VCC and off-state open load detection 27 3.5 Maximum demagnetization energy (VCC = 13.5V) . 29 4 Package and PCB thermal data . 30 4.1 PowerSSO-12 thermal data . 30 4.2 PowerSSO-24 thermal data . 32 5 Package and packing information . 36 5.1 ECOPACK . 36 5.2 PowerSSO-12 package information . 36 5.3 PowerSSO-24 package information . 38 5.4 PowerSSO-12 packing information . 40 5.5 PowerSSO-24 packing information . 41 6 Order codes . 42 7 Revision history . 43 2/44 Doc ID 14617 Rev 5
