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.

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.
