Description

The IRSF3021 Lamp and DC motor driver is a fully protected

three terminal monolithic Smart Power MOSFET that fea-

tures current limiting, over-temperature protection, ESD

protection and over-voltage protection.

The on-chip protection circuit limits the drain current at 5.5A

(typical) in the on-state, when the load is short circuited. The

over-temperature circuitry turns off the Power MOSFET when

the junction temperature exceeds 165°C (typical). The device

restarts automatically once it has cooled down below the reset

temperature.

The IRSF3021 is specifically designed for driving loads that

require overload protection and in-rush current control while

operating in automotive and industrial environments. Tar-

geted applications include resistive loads such as lamps or

capacitive loads such as airbag squibs and DC motor drives.
