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.
Automotive rated.
Replaces electromechanical relays and discrete circuits.
Linear mode capability - the current-limiting protection circuitry is designed to de-activate at
low V
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.
The current limit is programmable via an external resistor R
IN pins.
Status pin voltage reflects the gate drive being applied internally to the power MOSFET.
With V
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.
C compatible power switch for 12V and 24V DC applications.
