to +36 V
■ RoHS compliant
STEVAL-IFP010V3
If more than one channel is in overload, the TCSD
restart will not be simultaneous in order to prevent
high peak current from the supply. Non-
overloaded channels continue to operate
normally. The open-drain diagnostic outputs
indicate overtemperature conditions and open
load in the off-state.
Description
The STEVAL-IFP010V3 demonstration board is
based on the VNI2140J, a monolithic device
designed using ST’s VIPower technology for
driving two independent resistive or inductive
loads with one side connected to ground. Active
current limitation prevents a drop in system power
supply if the load is shorted. A built-in thermal
shutdown protects the chip from overtemperature
and short-circuit conditions. During an overload
condition, the channel turns off and back on
automatically in order to maintain the junction
temperature between TTSD and TR. If this
condition causes the case temperature to reach
TCSD, the overloaded channel is turned off and
will restart only when the case temperature has
decreased down to TCR.
