R 250 m ON restart (thermal shutdown) Current limitation (typ) I 5A LIMH Reverse battery protected (1) Off-state supply current I 2A S Electrostatic discharge protection 1. Typical value with all loads connected. Applications General All types of resistive, inductive and capacitive Inrush current active management by loads power limitation Suitable as LED driver Very low standby current Suitable as relays driver 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility Compliant with European directive The VNQ5E250AJ-E is a quad channel high-side 2002/95/EC driver manufactured using ST proprietary Very low current sense leakage VIPower M0-5 technology and housed in Diagnostic functions PowerSSO-16 package. The device is designed to drive 12 V automotive grounded loads, and to Proportional load current sense provide protection and diagnostics. It also High current sense precision for wide implements a 3 V and 5 V CMOS compatible currents range interface for the use with any microcontroller. Current sense disable The device integrates advanced protective Off-state open-load detection functions such as load current limitation, inrush Output short to V detection CC and overload active management by power Overload and short to ground (power limitation, overtemperature shut-off with auto- limitation) indication restart and overvoltage active clamp. A dedicated Thermal shutdown indication analog current sense pin is associated with every Protections output channel providing enhanced diagnostic functions including fast detection of overload and Undervoltage shutdown short-circuit to ground through power limitation Overvoltage clamp indication, overtemperature indication, short- Load current limitation circuit to V diagnosis and on-state and off-state CC Self limiting of fast thermal transients open-load detection. The current sensing and Protection against loss of ground and loss diagnostic feedback of the whole device can be of V CC disabled by pulling the CS DIS pin high to share the external sense resistor with similar devices.
