Provisional Data Sheet No. PD 6.068B

Description

The IRSF3021 Lamp and DC Motor Driver is a fully protected three

terminal monolithic SMART POWER MOSFET that features current

limiting, over-temperature protection, gate-to-source ESD protection

and gate-to-drain clamp for over-voltage protection.

The on-chip protection circuit limits the drain current in the on-state.

The over-temperature circuitry turns off the POWER MOSFET when

the junction temperature exceeds 165°C. The device restarts automati-

cally 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 auto-

motive and industrial environments. Targeted applications include

resistive loads such as lamps or capacitive loads such as airbag squibs

and DC motor drives.
