VNQ5E160AK-E Quad channel high side driver with analog current sense for automotive applications Features Max supply voltage V 41V CC Operating voltage range V 4.5 to 28 V CC PowerSSO-24 Max on-state resistance (per ch.) R 160 m ON Electrostatic discharge protection Current limitation (typ) I 10 A LIMH (1) Off state supply current I 2 A S Application 1. Typical value with all loads connected. All types of resistive, inductive and capacitive General loads Inrush current active management by Suitable as LED driver power limitation Very low stand-by current Description 3.0 V CMOS compatible inputs The VNQ5E160AK-E is a double channel high- Optimized electromagnetic emissions side driver manufactured in the ST proprietary Very low electromagnetic susceptibility VIPower M0-5 technology and housed in the tiny In compliance with the 2002/95/EC PowerSSO-24 package. The VNQ5E160AK-E is european directive designed to drive 12V automotive grounded loads Very low current sense leakage delivering protection, diagnostics and easy 3V and 5V CMOS compatible interface with any Diagnostic functions microcontroller. Proportional load current sense The device integrates advanced protective High current sense precision for wide functions such as load current limitation, inrush currents range and overload active management by power Current sense disable limitation, over-temperature shut-off with Off state openload detection auto-restart and over-voltage active clamp. A Output short to Vcc detection dedicated analog current sense pin is associated Thermal shutdown indication with every output channel in order to provide Overload and short to ground (power Ehnanced diagnostic functions including fast limitation) indication detection of overload and short-circuit to ground through power limitation indication, over- Protections temperature indication, short-circuit to Vcc Undervoltage shutdown diagnosis and on & off state open load detection. Overvoltage clamp The current sensing and diagnostic feedback of Load current limitation the whole device can be disabled by pulling the Self limiting of fast thermal transients CS DIS pin high to allow sharing of the external Protection against loss of ground and loss sense resistor with other similar devices. of V CC Over-temperature shutdown with autorestart (thermal shutdown) Reverse battery protected (see Figure 32) September 2013 Rev 3 1/37 www.st.com 1Contents VNQ5E160AK-E Contents 1 Block diagram and pin configuration . 5 2 Electrical specifications 7 2.1 Absolute 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 (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 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-24 thermal data . 29 5 Package and packing information . 32 5.1 ECOPACK . 32 5.2 PowerSSO-24 mechanical data 32 5.3 Packing information . 34 6 Order codes . 35 7 Revision history . 36 2/37
