VN5E050AJ-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 to 28V CC Max On-State resistance R 50 m PowerSSO-12 ON Current limitation (typ) I 27 A LIMH Reverse battery protected ( see Figure 32.) (1) Off state supply current I 2 A S Electrostatic discharge protection 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 Suitable as LED driver 3.0V CMOS compatible inputs Description Optimized electromagnetic emissions Very low electromagnetic susceptibility The VN5E050AJ-E 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 PowerSSO-12 package. The VN5E050AJ-E is designed to drive 12V automotive grounded loads Diagnostic functions delivering protection, diagnostics and easy 3V Proportional load current sense and 5V CMOS compatible interface with any High current sense precision for wide microcontroller. currents range The device integrates advanced protective Current sense disable functions such as load current limitation, inrush Off state open load detection and overload active management by power Output short to V detection CC limitation, over-temperature shut-off with Overload and short to ground (power auto-restart and over-voltage active clamp. A limitation) indication dedicated analog current sense pin is associated Thermal shutdown indication with every output channel in order to provide Ehnanced diagnostic functions including fast Protections detection of overload and short-circuit to ground Undervoltage shutdown through power limitation indication, over- Overvoltage clamp temperature indication, short-circuit to Vcc Load current limitation diagnosis and ON & OFF state open load Self limiting of fast thermal transients detection. Protection against loss of ground and loss The current sensing and diagnostic feedback of of V CC the whole device can be disabled by pulling the Over-temperature shutdown with CS DIS pin high to allow sharing of the external autorestart (thermal shutdown) sense resistor with other similar devices.
