IR2121 — Single MOSFET Gate Driver with Overcurrent Protection
The IR2121 (DIP-8) is a single-channel MOSFET gate driver IC from Infineon (formerly International Rectifier), featuring built-in overcurrent protection via a current sense input. It drives a single N-channel MOSFET with up to 1A peak output current and automatically shuts down the gate drive upon overcurrent detection — making it ideal for protected motor drives, solenoid drivers, and power switches in Pakistan.
