Description

The VNQ5027AK-E is a monolithic device made

using STMicroelectronics VIPower technology. It

is intended for driving resistive or inductive loads

with one side connected to ground. Active V

voltage clamp protects the device against low

energy spikes (see ISO7637 transient

compatibility table).

This device integrates an analog Current Sense

which delivers a current proportional to the load

current (according to a known ratio) when

CS_DIS is driven low or left open. When CS_DIS

is driven high, the CURRENT SENSE pin is in a

high impedance condition. Output current

limitation protects the device in overload

condition. In case of long overload duration, the

device limits the dissipated power to safe level up

to thermal shut-down intervention.

Thermal shut-down with automatic restart allows

the device to recover normal operation as soon as

fault condition disappears.
