VNQ5E050AK-E(2010) Datasheet - 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
