DESCRIPTION
The VN21 is a monolithic device made using
SGS-THOMSON Vertical Intelligent Power
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
VCC and overtemperature. Fast demagnetization
of inductive loads is archieved by negative (-18V)
load voltage at turn-off.
