Description

The VN808-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 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 TTSD

and TR. If this condition makes case temperature

reach TCSD, overloaded channel is turned OFF

and and will restart only when case temperature

has decreased down to TCR( see waveform 3

Figure 8 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
