The IR2121 from Infineon Technologies is a high-speed power MOSFET and IGBT driver featuring over-current limiting protection circuitry. It is designed for low-side applications and supports a gate drive supply range of 12V to 18V.
This monolithic IC utilizes Latch immune CMOS technology for rugged construction. Its logic inputs are compatible with standard CMOS or LSTTL outputs down to 2.5V logic. The output driver includes a high pulse current buffer stage designed for minimal cross-conduction. The integrated protection circuitry detects over-current in the driven power transistor and limits the gate drive voltage, with cycle-by-cycle shutdown programmed by an external capacitor.
The IR2121 is housed in an 8-PDIP package and is suitable for through-hole mounting. It offers features such as undervoltage lockout and an error lead that indicates fault conditions and programs shutdown time. The output is in phase with the input, and the device supports IGBT and N-Channel MOSFET gate driving.
Key electrical specifications include a supply voltage range of 12V to 18V, peak output current of 1A/2A, and typical rise times of 26ns to 43ns. The operating temperature range is -40°C to 150°C (TJ).
