VN5E050J-E Single channel high side driver for automotive applications Features Max 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 27A LIMH PowerSSO-12 (1) Off state supply current I 2 A S 1. Typical value with all loads connected. Application General All types of resistive, inductive and capacitive Inrush current active management by loads. power limitation Very low stand-by current Description 3.0V CMOS compatible inputs The VN5E050J-E is a single channel high-side Optimized electromagnetic emissions driver manufactured in the ST proprietary Very low electromagnetic susceptibility VIPower M0-5 technology and housed in the tiny In compliance with the 2002/95/EC PowerSSO-12 package. european directive The VN5E050J-E is designed to drive automotive Diagnostic functions grounded loads delivering protection, diagnostics Open Drain status output and easy 3V and 5V CMOS-compatible interface On-state open load detection with any microcontroller. Off-state open load detection The device integrates advanced protective Output short to V detection CC functions such as load current limitation, inrush Overload and short to ground (power and overload active management by power limitation) indication limitation, over-temperature shut-off with auto- Thermal shut-down indication restart and over-voltage active clamp. Protections A dedicated active low digital status pin is Undervoltage shut-down associated with every output channel in order to Overvoltage clamp provide Enhanced diagnostic functions including fast detection of overload and short-circuit to Load current limitation ground, over-temperature indication, short-circuit Self-limiting of fast thermal transients to V diagnosis and ON & OFF state open-load CC Protection against loss of ground and loss detection. of V CC The diagnostic feedback of the whole device can Over-temperature shut-down with be disabled by pulling the STAT DIS pin up, thus autorestart (thermal shut-down) allowing wired-ORing with other similar devices.
