DESCRIPTION
The VN16B 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
and overtemperature. Fast demagnetization

CC
of inductive loads is achieved by negative (-18V)
load voltage at turn-off.
Note: 2. The maximum continuous output current is the current at
Tc = 85 °C for a battery voltage of 13 V which does not
activate self protection.
