DESCRIPTION
The VN380 is a monolithic device made using
STM VIPower Technology, intended for driving
inductive loads. The inputs are CMOS
compatible. The diagnostic output provides an
indication of open load and demagnetization
mode. Built-in thermal shut-down protects the
chip from over-temperature. In case or
over-current or over-temperature or over-voltage
the product will automatically operate in
recirculation mode.
