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 short-
circuit. In overload condition, the channel turns
OFF and back ON automatically so as to maintain
junction temperature between T_TSD and T_R. If this
condition causes case temperature to reach
T_CSD, the overloaded channel is turned OFF and
restarts only when case temperature has
decreased down to T_CR. In the case of more than
one channel in overload, re-start of the
overloaded channels is not simultaneous, in order
to avoid high peak current from the supply. Non-
overloaded channels continue to operate
normally. The open drain diagnostic outputs
indicate overtemperature conditions.
