A8739EEETR-T

Overview

The A8739EEETR-T is a specialized power management IC designed as a photoflash capacitor charger, specifically tailored for xenon flash applications. Manufactured by Allegro MicroSystems, this component integrates high-efficiency charging circuitry within an 8-DFN or MLP package measuring 2x2 mm with a height of 0.60 mm. It operates as a single-function analog circuit suitable for mobile and portable imaging devices requiring reliable high-voltage capacitor charging.

Feature Summary

• Integrated photoflash capacitor charger architecture optimized for xenon flash systems
• Compact 8-DFN/MLP surface-mount package design for space-constrained PCB layouts
• High-efficiency power conversion capabilities for rapid capacitor charging cycles

Applications

• Xenon camera flash modules in smartphones
• Portable digital imaging devices
• Mobile phone peripheral lighting systems

Procurement Notes

Verify the exact package variant (8-DFN vs 10-DFN) against the specific datasheet revision, as sources indicate conflicting pin counts. Confirm availability status directly with authorized distributors, as some listings note restricted supply or regional sales limitations. Ensure the ordering suffix matches the required tape-and-reel configuration for automated assembly processes.

Selection Notes

Select this component when designing compact imaging systems requiring dedicated xenon flash charging. The small footprint supports dense board layouts typical in modern mobile devices. Evaluate thermal performance requirements given the power density of the 2x2 mm package. Ensure input voltage ranges align with the device's battery source specifications for optimal efficiency during flash recharge periods.

Part Context

This part belongs to Allegro MicroSystems' portfolio of specialized power management integrated circuits. While the manufacturer is widely recognized for Hall effect sensors, this specific model addresses niche power control needs in consumer electronics. It complements their broader analog circuit offerings by providing targeted solutions for high-voltage generation in portable optical equipment.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers should consult Allegro MicroSystems technical support for direct replacements or evaluate generic photoflash charger ICs from other manufacturers if pin-compatible alternatives are required.
