VN5E050MJ-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 V to 28V CC Max on-state resistance R 50 m PowerSSO-12 ON Current limitation (typ) I 27 A LIMH Electrostatic discharge protection (1) Off-state supply current I 2 A S 1. Typical value with all loads connected. Application All types of resistive, inductive and capacitive General loads Inrush current active management by Suitable as LED driver power limitation Very low standby current Description 3.0 V CMOS compatible inputs Optimized electromagnetic emissions The VN5E050MJ-E is a single channel high-side Very low electromagnetic susceptibility driver manufactured in the ST proprietary VIPower M0-5 technology and housed in the In compliance with the 2002/95/EC tiny PowerSSO-12 package. The VN5E050MJ-E european directive is designed to drive 12 V automotive grounded Very low current sense leakage loads delivering protection, diagnostics and easy Diagnostic functions 3 V and 5 V CMOS compatible interface with any Proportional load current sense microcontroller. High current sense precision for wide The device integrates advanced protective currents range functions such as load current limitation, inrush Current sense disable and overload active management by power Overload and short to ground (power limitation, overtemperature shut-off with limitation) indication auto-restart and overvoltage active clamp. A Thermal shutdown indication dedicated analog current sense pin is associated with every output channel in order to provide Protections Enhanced diagnostic functions including fast Undervoltage shutdown detection of overload and short-circuit to ground Overvoltage clamp through power limitation and overtemperature Load current limitation indication. 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 shutdown with auto sense resistor with other similar devices. restart (thermal shutdown) Reverse battery protected (see Figure 29) September 2013 Doc ID 16611 Rev 2 1/35 www.st.com 1Contents VN5E050MJ-E Contents 1 Block diagram and pin description . 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 20 3 Application information . 23 3.1 GND protection network against reverse battery . 23 3.1.1 Solution 1: resistor in the ground line (RGND only) 23 3.1.2 Solution 2: diode (D ) in the ground line 24 GND 3.2 Load dump protection 24 3.3 MCU I/O protection 24 3.4 Current sense and diagnostic 25 3.5 Maximum demagnetization energy (VCC = 13.5V) . 26 4 Package and PCB thermal data . 27 4.1 PowerSSO-12 thermal data . 27 5 Package information 30 5.1 ECOPACK . 30 5.2 Package mechanical data 30 5.3 Packing information . 32 6 Order codes . 33 7 Revision history . 34 2/35 Doc ID 16611 Rev 2
