– On state open load detection
– Off state open load detection
– Thermal shutdown indication
■ Protections
– Undervoltage shut-down
– Overvoltage clamp
– Output stuck to VCC detection
– Load current limitation
– Self limiting of fast thermal transients
– Protection against loss of ground and loss
of VCC
– Thermal shut down
– Reverse battery protection (see Figure 27)
– Electrostatic discharge protection

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 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 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.
