DESCRIPTION

The VND5012AK-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 VCC pin

voltage clamp protects the device against low

energy spikes (see ISO7637 transient

compatibility table).

ADVANCE DATA

PowerSSO-24

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.
