A8737EEJTR-T

Overview

The A8737EEJTR-T is a photoflash capacitor charger IC from Allegro MicroSystems, designed for xenon flash applications. It operates within a supply voltage range of 2.7V to 5.5V and supports output currents up to 1A for charging capacitors. The device features an integrated high-voltage switch capable of withstanding voltages up to 40V. Packaged in a compact 10-WFDFN (3x3mm) exposed pad footprint, it ensures efficient thermal performance and minimal board space consumption.

Feature Summary

• Integrated high-voltage power switch rated for 40V operation
• Dedicated architecture for rapid xenon photoflash capacitor charging
• Compact 10-pin WDFN package with exposed thermal pad

Applications

• Xenon flash capacitor charging in mobile devices
• Camera module power management systems
• Portable electronic imaging equipment

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the 10-WFDFN package dimensions match your PCB footprint requirements. Ensure compatibility with the target system's input voltage range of 2.7V to 5.5V before integration.

Selection Notes

Select this component when designing circuits requiring dedicated xenon flash charging capabilities. It is suitable for applications needing a compact solution with integrated high-voltage switching. Consider the thermal dissipation requirements associated with the exposed pad design during layout.
