STMicroelectronics
Description
The VNQ5E050AK-E is a quad channel high-side driver manufactured using ST proprietary VIPower™ M0-5 technology and housed in PowerSSO-24 package. The device is designed to drive 12 V automotive grounded loads, and to provide protection and diagnostics. It also implements a 3 V and 5 V CMOS compatible interface for the use with any microcontroller.
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 current sense precision for wide
currents range
– Current sense disable
– Off-state open-load detection
– Output short to VCC detection
– 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
Application
◾ All types of resistive, inductive and capacitive
loads
◾ Suitable as LED driver
