Description
The VND5050K-E and VND5050J-E are
monolithic devices made using
STMicroelectronics VIPower M0-5 technology.
they are intended for driving resistive or inductive
loads with one side connected to ground. Active
V_CC pin voltage clamp protects the devices
against low energy spikes (see ISO7637 transient
compatibility table). The devices detect 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, STATUS pin is in high impedance
state. Output current limitation protects the
devices in overload condition. In case of long
overload duration, the devices limit the dissipated
power to a safe level up to thermal shut-down
intervention. Thermal shut-down with automatic
restart allows the devices to recover normal
operation as soon as fault conditions disappear..
