DESCRIPTION
The VN920SP 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 V
CC
pin voltage
clamp protects the device against low energy
spikes (see ISO7637 transient compatibility
table). 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.
