Description
The VNI4140K-32 is a monolithic device made using STMicroelectronics VIPower technology, intended for driving four independent resistive, capacitive or inductive loads with one side connected to ground. Active current limitation avoids the system power supply dropping in the case of shorted load. Built-in thermal shutdown protects the chip from overtemperature and short­circuit. In overload condition, the channel turns OFF and back ON automatically so as to maintain junction temperature between T condition causes case temperature to reach T
, the overloaded channel is turned OFF and
CSD
restarts only when case temperature has decreased down to T
. In the case of more than
CR
one channel in overload, re-start of the overloaded channels is not simultaneous, in order to avoid high peak current from the supply. Non­overloaded channels continue to operate normally. The open drain diagnostic outputs indicate overtemperature conditions.
