IR2156STRPBF

Overview

The IR2156STRPBF is a half-bridge gate driver and ballast control IC in a 14-SOIC package. It integrates a high-voltage half-bridge driver with a programmable oscillator for fluorescent lamp applications. The device supports supply voltages from 10.5 V to 16.5 V, with output currents up to 500 mA. Operating frequencies range from 32 kHz to 60 kHz. It features programmable preheat time, run frequency, dead time, and over-current thresholds. The component operates within a temperature range of -40 °C to 125 °C.

Feature Summary

• Integrates a high-voltage half-bridge gate driver with a programmable oscillator for complete ballast control functionality.
• Features programmable parameters including preheat frequency, run frequency, preheat duration, and dead-time intervals.
• Includes comprehensive protection mechanisms such as under-voltage reset, latch immunity, ESD protection, and automatic restart upon fault conditions.

Applications

• Compact fluorescent lamp (CFL) electronic ballasts
• Linear fluorescent lamp electronic ballasts
• High-frequency AC lighting systems

Procurement Notes

Verify the specific suffix STRPBF confirms the tape-and-reel packaging format and lead-free RoHS compliance status. Confirm the lifecycle status, as documentation indicates this part may be Not Recommended for New Designs (NRND). Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements.

Selection Notes

Select this component for designs requiring integrated ballast control and half-bridge driving in a single package. It is suitable for applications needing adjustable operating frequencies and preheat times. Consider the SOIC-14 package constraints and thermal dissipation capabilities when designing the PCB layout for power management integration.

Part Context

This part belongs to the IR2156 family of ballast control ICs manufactured by Infineon Technologies. It combines the functions of a gate driver and a state machine controller. The STRPBF designation specifically identifies the surface-mount variant with tape-and-reel packaging, distinguishing it from through-hole or tube-packaged versions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative components due to the NRND status.
