IR2233J

IR2233J Description

The IR2233J from Infineon Technologies is a high-performance 6-channel gate driver IC designed for half-bridge and other power electronics applications. This surface-mount device, housed in a 44PLCC package, operates within a 10V to 20V supply range and supports high-side voltages up to 1200V (bootstrap configuration). With a peak output current capability of 250mA (source) and 500mA (sink), it ensures robust switching performance for power MOSFETs and IGBTs. The IR2233J is optimized for inverting logic inputs (VIL = 0.8V, VIH = 2V) and delivers fast switching with 90ns rise and 40ns fall times, minimizing power losses in high-frequency applications.

IR2233J Features

• High Voltage Tolerance: Supports 1200V bootstrap voltage, making it suitable for high-power systems.
• Fast Switching: 90ns rise / 40ns fall times enhance efficiency in high-frequency designs.
• Robust Drive Strength: 250mA source / 500mA sink current ensures reliable gate control.
