IR2161SPBF

Lighting, Ballast Controllers Overview

The IR2161 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high-side and low-side outputs. It features a wide supply voltage range from 10 V to 20 V for the logic supply and up to 500 V for the bootstrap supply. The device integrates a dead-time control function to prevent shoot-through in half-bridge configurations. It offers robust latch-up immunity and operates over an extended temperature range of -40°C to +125°C.

Lighting, Ballast Controllers Feature Summary

• Independent high-side and low-side output channels for half-bridge applications
• Integrated dead-time control mechanism to ensure safe switching transitions
• High-voltage tolerant inputs compatible with standard logic families
• Robust latch-up performance under high dv/dt conditions

Lighting, Ballast Controllers Applications

• Motor drive inverters
• Switched-mode power supplies
• Induction heating systems

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'SPBF' against Infineon's official documentation to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the exact package type and tape-and-reel specifications required for your assembly process. Cross-reference the datasheet revision date to confirm current manufacturing status.

Lighting, Ballast Controllers Selection Notes

Select this component when a dedicated half-bridge driver with integrated dead-time is required. Consider the 500 V blocking capability for medium-voltage applications. Evaluate the operating frequency requirements against the propagation delay specifications. Ensure the PCB layout supports the high-current output capabilities and thermal management needs.

Lighting, Ballast Controllers Part Context

This device belongs to the IR21xx series of high-voltage gate drivers. It is designed specifically for driving power switches in bridge configurations. The series is widely used in industrial and consumer applications requiring reliable high-side switching. It complements other drivers in the lineup by offering integrated timing control.

Lighting, Ballast Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as the IR2167 or IR2169, which may offer similar functionality. Verify that any substitute maintains the same voltage ratings and output current capabilities. Confirm compatibility with existing dead-time settings and logic input levels.
