Description
The VND5050K-E and VND5050J-E is a
monolithic device made using STMicroelectronics
VIPower M0-5 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, STATUS pin is in
high impedance state.
Output current limitation protects the device in
overload condition. In case of long overload
duration, 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..
