INFINEON IR2121PBF Power MOSFET Driver
The IR2121PBF is a high-speed power MOSFET and IGBT driver featuring over-current limiting protection circuitry. Its latch-immune CMOS technology enables ruggedized monolithic construction. The device's logic inputs are compatible with standard CMOS or LSTTL outputs and can operate down to 2.5V logic levels. The output driver includes a high pulse current buffer designed to minimize cross-conduction. Integrated protection circuitry detects over-current conditions in the driven power transistor and limits the gate drive voltage accordingly. Cycle-by-cycle shutdown is managed via an external capacitor, which controls the time interval between over-current detection and shutdown. The output can drive N-channel power MOSFETs or IGBTs in low-side configurations. Additional features include under-voltage lockout, current detection and limiting, fault indication through an error lead, and phase-aligned output with respect to input. The device supports 2.5V, 5V, and 15V logic inputs. Suitable for applications in industrial and consumer electronics.
