VN5E025AJ-E Single channel high-side driver with analog current sense for automotive applications Features Max supply voltage V 41 V CC Operating voltage range V 4.5 to 28 V CC Max On-State resistance R 25 m ON Current limitation (typ) I 60 A LIMH PowerSSO-12 (1) Off state supply current I 2A S Reverse battery protected 1. Typical value with all loads connected. Electrostatic discharge protection General Application Inrush current active management by power limitation All types of resistive, inductive and capacitive loads Very low stand-by current 3.0 V CMOS compatible inputs Suitable as LED driver Optimized electromagnetic emissions Description Very low electromagnetic susceptibility In compliance with the 2002/95/EC The VN5E025AJ-E is a single channel high-side european directive driver manufactured in the ST proprietary Very low current sense leakage VIPower M0-5 technology and housed in the tiny PowerSSO-12 package. The VN5E025AJ-E is Diagnostic functions designed to drive 12 V automotive grounded Proportional load current sense loads delivering protection, diagnostics and easy High current sense precision for wide 3 V and 5 V CMOS compatible interface with any currents range microcontroller. Current sense disable The device integrates advanced protective Off state openload detection functions such as load current limitation, inrush Output short to V detection CC and overload active management by power Overload and short to ground (power limitation, over-temperature shut-off with auto- limitation) indication restart and over-voltage active clamp. A dedicated Thermal shutdown indication analog current sense pin is associated with every output channel in order to provide Ehnanced Protections diagnostic functions including fast detection of Undervoltage shutdown overload and short-circuit to ground through Overvoltage clamp power limitation indication, over-temperature Load current limitation indication, short-circuit to V diagnosis and ON- CC Self limiting of fast thermal transients state and OFF-state open load detection. Protection against loss of ground and loss The current sensing and diagnostic feedback of of V CC the whole device can be disabled by pulling the Over-temperature shutdown with CS DIS pin high to allow sharing of the external autorestart (thermal shutdown) sense resistor with other similar devices September 2013 Doc ID 13106 Rev 5 1/37 www.st.com 1Contents VN5E025AJ-E Contents 1 Block diagram and pin description . 5 2 Electrical specifications 7 2.1 Absolue maximum ratings . 7 2.2 Thermal data . 8 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 (D ) in the ground line 25 GND 3.2 Load dump protection 25 3.3 MCU I/O protection 25 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) . 28 4 Package and PC board thermal data . 29 4.1 PowerSSO-12 thermal data . 29 5 Package and packing information . 32 5.1 ECOPACK packages . 32 5.2 PowerSSO-12 mechanical data 32 5.3 Packing information . 34 6 Order codes . 35 7 Revision history . 36 2/37 Doc ID 13106 Rev 5
