Description

This 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 the dropping of system power supply in

case of a shorted load. Built-in thermal shutdown

protects the chip from over-temperature and

short-circuit. In overload condition, channel turns

OFF and back ON automatically in order to

maintain the junction temperature between TTSD

and TR. If this condition causes case temperature

to reach TCSD, the overloaded channel is turned

OFF and will restart only when case temperature

has decreased down to TCR.

In cases where 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

diagnostics output indicates over-temperature.
