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 VCC pin
voltage clamp protects the device against low
energy spikes (see ISO7637 transient
compatibility table).

ADVANCE DATA
PowerSSO-24
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 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.
