Description

The VNQ5050K-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

pin voltage clamp protects the

device against low energy spikes (see ISO7637

transient compatibility table).

The device detects open load condition both in on

and off-state, when STAT_DIS is left open or

driven low. Output shorted to Vcc is detected in

the off-state.

When STAT_DIS is driven high, the STATUS 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.
