Description

The VN808-32-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.

PowerSO-36

Active current limitation combined with thermal shutdown and automatic restart, protect the device against overload. In overload condition, channel turns OFF and back ON automatically so as to maintain junction temperature between T

TSD

and TR. If this condition makes case temperature reach T

, overloaded channel is turned OFF

CSD

and will restart only when case temperature has decreased down to T

(see waveform 3 Figure 8

CR

on page 11). Non overloaded channels continue

to operate normally. Device automatically turns OFF in case of ground pin disconnection. This device is especially suitable for industrial applications conform to IEC 61131.
