A8732EEETR-T

Overview

The A8732EEETR-T is a dedicated power management integrated circuit designed for xenon camera flash capacitor charging. It operates within a supply voltage range of 1.5V to 5.5V and draws a typical supply current of 50µA. The device is housed in an 8-UFDFN package with exposed pad, measuring 2x2mm. It supports an operating temperature range from -40°C to +85°C. This component functions as a specialized PMIC for managing energy storage in photographic applications.

Feature Summary

• Dedicated controller architecture optimized for xenon flash capacitor charging cycles
• Low quiescent current consumption suitable for battery-powered portable devices
• Integrated protection features inherent to the specific PMIC design

Applications

• Camera flash capacitor charger circuits
• Xenon lamp power management systems
• Portable digital camera power supplies

Procurement Notes

Verify component authenticity through authorized Allegro MicroSystems distributors or certified secondary market suppliers like Rochester Electronics. Confirm lot codes and date codes against current manufacturing records. Ensure packaging integrity matches standard reel specifications. Request original datasheets and test reports to validate performance parameters before integration into production designs.

Selection Notes

Select this component specifically for xenon-based flash charging applications requiring low standby current. Evaluate thermal dissipation requirements given the small 8-DFN footprint. Compare against newer Allegro PMICs if long-term availability is critical, as this part may have limited future production runs. Ensure input voltage ranges match the system's battery configuration.

Part Context

This part belongs to the A8732 series of dedicated power management ICs. It is distinct from Allegro's magnetic sensors and motor drivers. The device addresses the specific high-voltage charging needs of xenon flashes in compact electronic imaging devices, differentiating it from general-purpose charge pumps.

Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Check with Allegro MicroSystems for end-of-life notifications or recommended obsolescence alternatives.
