Applications

• 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

• μC Compatible Power Switch for 12V and 24V DC Applications

• Replaces Electromechanical Relays and Discrete Circuits

• Linear Mode Capability - The current-limiting protection circuitry is designed to deactivate at low VDS in order not to compromise the load current during normal operation. The design 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.

• Current Limit is Programmable via an External Resistor RPROG Connected Between Status and IN pins

• Status Pin Voltage Reflects the Gate Drive Applied Internally to the Power MOSFET

• With VIN = 5V and RPROG = 24kΩ:

 Status Voltage: 5V Indicates Normal Operation

 Status Voltage: 2V to 3V Indicates the Device is in Current-Limiting Mode

 Status Voltage
