DESCRIPTION
The VN31 is a monolithic device made using
STMicroelectronics
VIPower
Technology,
intended for driving resistive or inductive loads
with one side grounded.
Built-in thermal shut-down protects the chip from
over temperature and short circuit.
The open drain diagnostic output indicates: open
load in off state and in on state, output shorted to
V
CC
and overtemperature. Fast demagnetization
of inductive loads is achieved by negative (-18V)
load voltage at turn-off.
