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 VCC 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.
