Description

The VNI4140K-32 is a monolithic device made

using STMicroelectronics VIPower technology,

intended to drive four independent resistive,

capacitive or inductive loads with one side

connected to ground. Active current limitation

avoids the system power supply dropping in case

of shorted load. Built-in thermal shutdown

protects the chip from overtemperature and short-

circuit. In overload conditions, the channel turns

OFF and back ON automatically so to maintain

junction temperature between TTSD and TR. If this

condition causes case temperature to reach

TCSD, the overloaded channel is turned OFF and

restarts 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 diagnostic outputs indicate

overtemperature conditions.
