IRSF3031

Data Sheet No. PD 60068-I (NOTE: For new designs, we recommend IR’s new products IPS021 and IPS021L) IRSF3021 FULLY PROTECTED POWER MOSFET SWITCH Features Controlled slew rate reduces EMI Over temperature protection with auto-restart Linear current-limit protection Active drain-to-source clamp ESD protection Lead compatible with standard Power MOSFET Low operating input current Monolithic construction Product Summary Vds(clamp) Rds(on) Ilim Tj(sd) EAS Applications Cabin Lighting Airbag System Programmable Logic Controller DC Motor Drive 50V 200mΩ 5.5A 165 oC 200mJ 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, 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. Targeted applications include resistive loads such as lamps or capacitive loads such as airbag squibs and DC motor drives. Packages 3 Lead TO220AB 3 Lead SOT223 Block Diagram...
