DESCRIPTION
The VNQ5050K-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 V_CC 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 V_CC 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 duration over-
load, the device limits the dissipated power to safe
level up to thermal shut-down intervention. . Ther-
mal shut-down with automatic restart allows the
device to recover normal operation as soon as
fault condition disappears.
