Description

The VNQ5050AK-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. Active V

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

a safe level up to thermal shutdown intervention.

Thermal shutdown with automatic restart allows

the device to recover normal operation as soon as

the fault condition disappears.

– Reverse battery protection (see

– Electrostatic discharge protection

All types of resistive, inductive and capacitive

loads.

Suitable as LED driver.
