1 / 37 page  September 2013 Doc ID 15609 Rev 4 1/37 1 VN5E160AS-E Single channel high side driver with analog for automotive applications Features ■ General – Inrush current active management by power limitation – Very low standby current – 3.0 V CMOS compatible inputs – Optimized electromagnetic emission – Very low electromagnetic susceptibility – In compliance with the 2002/95/EC european directive – Very low current sense leakage ■ Diagnostic functions – Proportional load current sense – High-precision current sense for wide-range currents – Current sense disable – OFF-state open-load detection – Output short to VCC detection – Overload and short to ground (power limitation) 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 autorestart (thermal shutdown) – Reverse battery protected – Electrostatic discharge protection Application ■ All types of resistive, inductive and capacitive loads ■ Suitable as LED driver Description The VN5E160AS-E is a single-channel high-side driver manufactured in the ST proprietary VIPower™ M0-5 technology and housed in the tiny SO-8 package. The VN5E160AS-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 in order to provide ehnanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication, overtemperature indication, short-circuit to VCC diagnosis and ON & 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. Max supply voltage VCC 41 V Operating voltage range VCC 4.5 V to 28 V Max ON-state resistance (per ch.) RON 160 m Ω Current limitation (typ) ILIMH 10 A OFF-state supply current IS 2 µA(1) 1. Typical value with all loads connected. www.st.com |
