Description

The VNI4140K is a monolithic device made using

STMicroelectronics VIPower technology, intended

to drive four independent resistive or inductive

loads with one side connected to ground. Active

current limitation avoids dropping the system

power supply in case of shorted load. Built-in

thermal shutdown protects the chip from

overtemperature and short-circuit. In overload

conditions, channel turns OFF and back ON

automatically so to maintain junction temperature

between TTSD and TR. If this condition makes

case temperature reach TCSD, overloaded

channel is turned OFF and restart only when case

temperature has decreased down to TCR. In case

of more than one channel in overload, restart of

the overloaded channels is not simultaneous, in

order to avoid high peak current from the supply.

Non-overloaded channels continue operating

normally. The open drain diagnostics outputs

indicate overtemperature conditions.
