VNQ5E160K-E Quad channel high side driver for automotive applications Features Max transient supply voltage V 41V CC Operating voltage range V 4.5 to 28V CC Max on-state resistance (per ch.) R 160 m ON Current limitation (typ) I 10 A LIMH PowerSSO-24 (1) Off-state supply current I 2 A S 1. Typical value with all loads connected. Application General Inrush current active management by All types of resistive, inductive and capacitive power limitation loads Very low standby current 3.0V CMOS compatible inputs Description Optimized electromagnetic emissions The VNQ5E160K-E is a quad channel high-side Very low electromagnetic susceptibility driver manufactured in the ST proprietary In compliance with the 2002/95/EC VIPower M0-5 technology and housed in the tiny european directive PowerSSO-24 package. Diagnostic functions The VNQ5E160K-E is designed to drive automotive Open Drain status output grounded loads delivering protection, diagnostics On-state open load detection and easy 3V and 5V CMOS-compatible interface Off-state open load detection with any microcontroller. Output short to V detection CC The device integrates advanced protective Overload and short to ground (power functions such as load current limitation, inrush limitation) indication and overload active management by power Thermal shutdown indication limitation, over temperature shut-off with auto restart and over-voltage active clamp. Protections Undervoltage shut-down A dedicated active low digital status pin is associated with every output channel in order to Overvoltage clamp provide Enhanced diagnostic functions including Load current limitation fast detection of overload and short-circuit to Self limiting of fast thermal transients ground, over temperature indication, short-circuit Protection against loss of ground and loss to V diagnosis and ON & OFF-state open-load CC of V CC detection. Over temperature shutdown with auto The diagnostic feedback of the whole device can restart (thermal shutdown) be disabled by pulling the STAT DIS pin up, thus Reverse battery protected (see Application allowing wired-ORing with other similar devices. schematic on page 22) Electrostatic discharge protection September 2013 Doc ID 14471 Rev 4 1/34 www.st.com 1 Contents VNQ5E160K-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 15 2.5 Electrical characteristics curves 19 3 Application information . 22 3.1 GND protection network against reverse battery . 22 3.1.1 Solution 1: resistor in the ground line (RGND only) 22 3.1.2 Solution 2: diode (DGND) in the ground line . 23 3.2 Load dump protection 23 3.3 MCU I/Os protection . 23 3.4 Open-load detection in off-state 24 3.5 Maximum demagnetization energy (VCC = 13.5V) . 25 4 Package and PC board thermal data . 26 4.1 PowerSSO-24 thermal data . 26 5 Package and packing information . 29 5.1 ECOPACK packages . 29 5.2 PowerSSO-24 mechanical data 29 5.3 Packing information . 31 6 Order codes . 32 7 Revision history . 33 2/34 Doc ID 14471 Rev 4
