RON 16 mΩ Current limitation (typ) ILIMH 73 A Off-state supply current IS 2 µA(1) 1. Typical value with all loads connected. • • • General – Inrush current active management by power limitation – Very low standby current – 3.0 V CMOS compatible inputs – Optimized electromagnetic emissions – Very low electromagnetic susceptibility – In compliance with the 2002/95/EC European directive Diagnostic functions – Proportional load current sense – High current sense precision for wide current range – Current sense disable – Off-state open-load detection – Output short to VCC indication – Overload and short to ground (power limitation) indication – Thermal shutdown indication Protections – Undervoltage shutdown – Overvoltage clamp – Load current limitation – Self limiting of fast thermal transients – Protection against loss of ground and loss of VCC – Overtemperature shutdown with auto restart (thermal shutdown) September 2013 – Reverse battery protected – Electrostatic discharge protection Applications • All types of resistive, inductive and capacitive loads • Suitable as LED driver Description The VN5E016AH-E is a single channel high-side driver manufactured in the ST proprietary VIPower™ M0-5 technology and housed in the tiny HPak package. The VN5E016AH-E is designed to drive 12 V automotive grounded loads delivering protection, diagnostics and easy 3 V and 5 V CMOS compatible interface with any microcontroller. The device integrates advanced protective functions such as load current limitation, inrush and overload active management by power limitation, overtemperature shut-off with auto restart and overvoltage active clamp. A dedicated analog current sense pin is associated with every output channel to provide enhanced diagnostic functions. These functions include fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to VCC diagnosis and ON-state and OFF-state open-load detection. The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to allow sharing of the external sense resistor with other similar devices.
