ON-state resistance R 10 m ON Current limitation (typ) I 85 A LIMH Reverse battery protection with self switch (1) OFF-state supply current I 2 A S on of the Power MOSFET (see Figure 32) Electrostatic discharge protection 1. Typical value with all loads connected Applications General Inrush current active management by All types of resistive, inductive and capacitive power limitation loads Very low standby current Suitable as LED driver 3 V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility The VN5E010AH is a single-channel high-side In compliance with the 2002/95/EC driver manufactured in the ST proprietary european directive VIPower M0-5 technology and housed in the tiny Very low current sense leakage HPAK package. The VN5E010AH is designed to Diagnostic functions drive 12 V automotive grounded loads delivering Proportional load current sense protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any High current sense precision for wide microcontroller. current range Current sense disable The device integrates advanced protective OFF-state open-load detection functions such as load current limitation, inrush and overload active management by power Output short to V detection CC limitation, overtemperature shut-off with auto- Overload and short to ground (power restart and overvoltage active clamp. A dedicated limitation) indication analog current sense pin is associated with every Thermal shutdown indication output channel in order to provide ehnanced Protection diagnostic functions including fast detection of Undervoltage shutdown overload and short-circuit to ground through power limitation indication, overtemperature Overvoltage clamp indication, short-circuit to Vcc diagnosis and Load current limitation ON- and OFF-state open-load detection. Self limiting of fast thermal transients The current sensing and diagnostic feedback of Protection against loss of ground and loss the whole device can be disabled by pulling the of V CC CS DIS pin high to allow sharing of the external Overtemperature shut down with sense resistor with other similar devices. autorestart (thermal shutdown) September 2013 Doc ID 15984 Rev 3 1/37 www.st.com 1 Contents VN5E010AH 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 Load dump protection 24 3.2 MCU I/Os protection . 24 3.3 Current sense and diagnostic 25 3.3.1 Short to VCC and OFF-state open-load detection . 26 3.4 Maximum demagnetization energy (VCC = 13.5 V) . 27 4 Package and PC board thermal data . 28 4.1 HPAK thermal data 28 5 Package and packing information . 31 31 5.1 ECOPACK 5.2 HPAK mechanical data . 31 5.3 HPAK suggested land pattern . 33 5.4 Packing information . 34 6 Order codes . 35 7 Revision history . 36 2/37 Doc ID 15984 Rev 3
