Applications and information

•

Especially suited for loads with a high in-rush current such as lamps and motors.

•

All types of resistive, inductive and capacitive loads in switching applications.

•

C compatible power switch for 12V and 24V DC applications.

•

Automotive rated.

•

Replaces electromechanical relays and discrete circuits.

•

Linear mode capability - the current-limiting protection circuitry is designed to de-activate at

max. DC operating current is therefore determined by the thermal capability of the package/

board combination, rather than by the protection circuitry.

Note: This does not compromise the product's ability to self-protect during short-circuit load

conditions.

•

IN pins.

•

Status pin voltage reflects the gate drive being applied internally to the power MOSFET.

Status voltage ~ 5V indicates normal operation.

Status voltage ~ (2-3)V indicates that the device is in current-limiting mode.

Status voltage < 1V indicates that the device is in thermal shutdown.
