IR2156STR

Lighting, Ballast Controllers Overview

The IR2156STR is a half-bridge gate driver integrated with ballast control functions, designed for electronic lighting applications. It operates within a supply voltage range of 10 V to 25 V and provides output currents of 400 mA sink and 250 mA source. The device features rise and fall times of 110 ns and 55 ns respectively. It is housed in a 14-lead SOIC package and supports operation temperatures from -25°C to +125°C.

Lighting, Ballast Controllers Feature Summary

• Integrates high-voltage half-bridge gate driver with programmable oscillator and state diagram for complete ballast control.
• Features programmable preheat frequency, preheat time, dead-time, and run frequency for optimized lamp performance.
• Includes comprehensive protection mechanisms such as over-current threshold, under-voltage reset, and latch immunity.

Lighting, Ballast Controllers Applications

• Electronic ballast controllers for fluorescent lighting
• Single-lamp electronic ballast systems
• Resonant half-bridge power conversion circuits

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'STR' against official Infineon documentation to confirm tape-and-reel packaging status. Confirm RoHS compliance details and lifecycle status, as this component may be designated as Not Recommended for New Designs (NRND). Ensure moisture sensitivity level handling procedures are followed during assembly.

Lighting, Ballast Controllers Selection Notes

Select this component when a combined gate driver and ballast controller is required for single-lamp fluorescent applications. Consider the 14-lead SOIC package constraints and the specific operating temperature range. Evaluate if the programmable parameters meet the design requirements for preheat and run frequencies without external timing components.

Lighting, Ballast Controllers Part Context

The IR2156 series belongs to Infineon's family of lighting drivers and controller ICs. It combines power management and logic control in a single chip, reducing component count in electronic ballast designs. The STR variant typically denotes a reel-packaged version of the standard IR2156S part.

Lighting, Ballast Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Verify compatibility with existing circuit layouts if substituting with other IR215x series variants or equivalent ballast controllers from other manufacturers.
