IR2112SPBF

IR2112SPBF Description

The IR2112SPBF from Infineon Technologies is a high-voltage, high-speed gate driver IC designed for driving MOSFETs and IGBTs in half-bridge or full-bridge configurations. This surface-mount (SOIC-16) device integrates independent high-side and low-side drivers with a 600V bootstrap capability, making it suitable for high-power switching applications. Operating within a 10V to 20V supply range, it delivers peak output currents of 250mA (source) and 500mA (sink), ensuring robust switching performance. Although marked as "Not For New Designs", it remains a reliable choice for legacy systems requiring high-voltage isolation and fast switching (typ. 80ns rise / 40ns fall times).

IR2112SPBF Features

• High-Side Voltage Support: Bootstrap voltage up to 600V for driving high-side MOSFETs/IGBTs.
• Fast Switching: Optimized 80ns rise and 40ns fall times minimize switching losses.
• Dual Independent Channels: High-side and low-side drivers for flexible half/full-bridge designs.
• Robust Drive Current: 250mA source / 500mA sink ensures quick turn-on/off of power devices.
• Wide Logic Compatibility: 6V (VIL) / 9.5V (VIH) thresholds for interfacing with 3.3V, 5V, or 15V logic.
• Reliability Compliance: ROHS3 and REACH compliant, with MSL 3 (168 hours) moisture sensitivity.

IR2112SPBF Applications

• Motor Drives: Ideal for BLDC/PMSM motor control in industrial and automotive systems.
• Power Converters: Used in AC-DC, DC-DC converters, and inverters for renewable energy systems.
• Switching Power Supplies: High-efficiency SMPS designs requiring high-voltage isolation.
• Industrial Automation: Drives IGBTs in PLCs, robotics, and servo drives.
• Legacy Systems: Suitable for maintaining/upgrading older high-voltage designs.
