Description

The VN808SR 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,

the channel turns OFF and back ON

automatically so as to maintain the junction

temperature between TTSD and TR. If this

condition makes the case temperature reach

TCSD, the overloaded channel is turned OFF and

restarts only when the case temperature has

decreased to TCR (see waveform 3 Figure 7 on

page 10). Non overloaded channels continue to

operate normally. The device automatically turns

OFF in the case of a ground pin disconnection.

This device is especially suitable for industrial

applications and conforms to IEC 61131.
