■ CMOS compatible input
■ Junction over-temperature protection
■ Case over-temperature protection for thermal
independence of the channels
■ Current limitation
■ Shorted load protection
■ Undervoltage shut-down
■ Protection against loss of ground
■ Very low stand-by current
■ Compliance to 61000-4-4 IEC test up to 4 kV
Description
The VN808CM-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.
Figure 1. Block diagram
PowerSO-36
It can be driven by using a 3.3 V logic supply.
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 will restart only when case temperature has
decreased down to TCR(see waveform 3 Figure 6
on page 10). 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
