Description
The VN5050J-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
overload, the device limits the dissipated power to
safe level up to thermal shut-down intervention.
Thermal shut-down with automatic restart allows
the device to recover normal operation as soon as
fault condition disappears..
