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.
