VN5E160MS-E Single-channel high-side driver with analog for automotive applications Features Max supply voltage V 41 V CC Operating voltage range V 4.5 V to 28 V CC 62 Max ON-state resistance 1( 5 R 160 m ON (per ch.) Electrostatic discharge protection Current limitation (typ) I 10 A LIMH (1) OFF-state supply current I 2 A Applications S 1. Typical value with all loads connected. All types of resistive, inductive and capacitive loads General Suitable as LED driver Inrush current active management by power limitation Description Very low standby current The VN5E160MS-E is a single-channel high-side 3.0 V CMOS compatible inputs driver manufactured in the ST proprietary Optimized electromagnetic emission VIPower M0-5 technology and housed in the Very low electromagnetic susceptibility tiny SO-8 package. The VN5E160MS-E is In compliance with the 2002/95/EC designed to drive 12 V automotive grounded european directive loads delivering protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any Very low current sense leakage microcontroller. Diagnostic functions The device integrates advanced protective Proportional load current sense functions such as load current limitation, inrush High-precision current sense for and overload active management by power wide currents range limitation, overtemperature shut-off with Current sense disable auto-restart and overvoltage active clamp. Overload and short to ground A dedicated analog current sense pin is (power limitation) indication associated with every output channel in order to Thermal shutdown indication provide enhanced diagnostic functions including fast detection of overload and short-circuit to Protections ground through power limitation indication and Undervoltage shutdown overtemperature indication. 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 Overtemperature shutdown with autorestart (thermal shutdown) Reverse battery protected September 2013 Doc ID 15730 Rev 4 1/34 www.st.com 1 Contents VN5E160MS-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 17 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: a diode (DGND) in the ground line . 23 3.2 Load dump protection 23 3.3 MCU I/Os protection . 23 3.4 Current sense and diagnostic 24 3.5 Maximum demagnetization energy (VCC = 13.5 V) . 25 4 Package and PCB thermal data . 26 4.1 SO-8 thermal data 26 5 Package and packing information . 29 29 5.1 ECOPACK 5.2 Package mechanical data 29 5.3 Packing information . 31 6 Order codes . 32 7 Revision history . 33 2/34 Doc ID 15730 Rev 4
