VNQ5E050K-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 50 m ON Current limitation (typ) I 27 A LIMH PowerSSO-24 (1) Off-state supply current I 2 A S Electrostatic discharge protection 1. Typical value with all loads connected. General Applications Inrush current active management by power limitation All types of resistive, inductive and capacitive Very low stand-by current loads 3.0 V CMOS compatible inputs Optimized electromagnetic emissions Description Very low electromagnetic susceptibility The VNQ5E050K-E is a quad 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 Diagnostic functions tiny PowerSSO-24 package. Open drain status output The VNQ5E050K-E is designed to drive automotive On-state open-load detection grounded loads delivering protection, diagnostics Off-state open-load detection and an easy 3 V and 5 V CMOS compatible Output short to Vcc detection interface with any microcontroller. Overload and short to ground (power The device integrates advanced protective limitation) indication functions such as load current limitation, inrush Thermal shutdown indication and overload active management by power Protections limitation, over temperature shut-off with auto restart and over-voltage active clamp. Undervoltage shutdown Overvoltage clamp A dedicated active low digital status pin is Load current limitation associated with every output channel in order to provide Enhanced diagnostic functions including Self limiting of fast thermal transients fast detection of overload and short-circuit to Protection against loss of ground and loss ground, over temperature indication, short-circuit of V CC to V diagnosis and ON & OFF-state open-load CC Over temperature shutdown with auto detection. restart (thermal shutdown) The diagnostic feedback of the whole device can Reverse battery protected (see Application (1) be disabled by pulling the STAT DIS pin up, thus schematic on page 22) allowing wired-ORing with other similar devices.
