The VND810-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.
Activ e V
pin voltage clamp pro tects the device
CC
against low energy spikes (see ISO7637 transient
compatibility table).
Figure 1. Package
SO-16
Active current limitation combined with thermal
shutdown and automatic restart protects the
device against overload. The device detects open
load condition both in on and off state. Output
shor te d to V
is detected in the off state. Device
CC
automatically turns off in case of ground pin
disconnection.
