DESCRIPTION
The VN920SP-E is a monolithic device designed
in STMicroelectronics VIPower M0-3 Technology,
intended for driving any kind of load with one side
connected to ground. Active VCC pin voltage
clamp protects the device against low energy
spikes (see ISO7637 transient compatibility table).

PowerSO-10™
Active current limitation combined with thermal
shutdown and automatic restart protect the device
against overload. The device integrates an analog
current sense output which delivers a current
proportional to the load current. Device
automatically turns off in case of ground pin
disconnection.

Note: 2. To ensure long term reliability under heavy overload or short circuit conditions, protection and related diagnostic signals must be
used together with a proper software strategy. If the device is subjected to abnormal conditions, this software must limit the duration
and number of activation cycles.
