Description
The VN920D-B5 and VN920DSO are monolithic devices designed in STMicroelectronics VIPower M0-3 technology. The VN920D-B5 and VN920DSO are intended for driving any type of load with one side connected to ground. The active VCC pin voltage clamp protects the devices against low energy spikes (see ISO7637 transient compatibility table).
Active current limitation combined with thermal shutdown and automatic restart protects the devices against overload. The devices detect the open load condition in both the on and off-state. In the off-state the devices detect if the output is shorted to VCC. The devices automatically turn-off in the case where the ground pin becomes disconnected.
