ST VND5050KTR-E

The VND5050K-E and VND5050J-E are monolithic devices made using VIPower M0-5 technology. They are intended for driving resistive or inductive loads with one side connected to ground. Active VCC pin voltage clamp protects the devices against low energy spikes. The devices detect 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 devices in overload condition. In case of long overload duration, the devices limit the dissipated power to a safe level up to thermal shutdown intervention. Thermal shutdown with automatic restart allows the devices to recover normal operation as soon as fault conditions disappear.
