DISSIPATION

DESCRIPTION

The VN21 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

of inductive loads is achieved by negative (-18V)

load voltage at turn-off.

Note: 2. The maximum continuous output current is the current at
