1 / 40 page  September 2013 Doc ID 022514 Rev 2 1/40 1 VND5E050MCJ-E VND5E050MCK-E Double-channel high-side driver with analog current sense for automotive applications Features ■ 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 – Compliance with European directive 2002/95/EC – Very low current sense leakage ■ Diagnostic functions – Proportional load current sense – High-precision current sense for wide currents range – Current sense disable – 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) – Reverse battery protected – Electrostatic discharge protection Applications ■ All types of resistive, inductive and capacitive loads ■ Suitable as LED driver Description The VND5E050MCJ-E and VND5E050MCK-E are double channel high-side drivers manufactured using ST proprietary VIPower® M0-5 technology and housed in PowerSSO-12 and PowerSSO-24 packages. The devices are designed to drive 12 V automotive grounded loads, and to provide protection and diagnostics. They also implement a 3 V and 5 V CMOS- compatible interface for the use with any microcontroller. The devices integrate 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 providing enhanced diagnostic functions including fast detection of overload and short-circuit to ground through power limitation indication and overtemperature indication. The current sensing and diagnostic feedback of the whole device can be disabled by pulling the CS_DIS pin high to share the external sense resistor with similar devices. Max transient supply voltage VCC 41 V Operating voltage range VCC 4.5 V to 28 V Max on-state resistance (per ch.) RON 50 m Current limitation (typ) ILIMH 27 A Off-state supply current IS 2 µA(1) 1. Typical value with all loads connected. PowerSSO-24 PowerSSO-12 www.st.com |
