Description

The VND5025LAK-E is a monolithic device made

using STMicroelectronics VIPower M0-5

technology. It is intended for driving resistive or

inductive loads with one side connected to

ground, and suitable for driving LEDs.

Active V

pin 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 shutdown intervention.

Thermal shutdown with automatic restart allows

the device to recover normal operation as soon as

fault condition disappears.
