A8735EEETR-T

Overview

The A8735EEETR-T is a dedicated 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 pads, measuring 2x2mm. It supports surface mount installation and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Dedicated controller for charging capacitors in xenon flash systems
• Optimized for low power consumption during standby operations
• Compact surface-mount footprint suitable for space-constrained designs

Applications

• Camera flash capacitor charger
• Xenon PMIC applications

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm that the 8-DFN/MLP(2x2) package matches design requirements. Check RoHS3 compliance documentation for regulatory adherence. Ensure replacement strategies are defined due to end-of-life status.

Selection Notes

Select this component specifically for xenon flash capacitor charging tasks requiring minimal quiescent current. Verify compatibility with the 1.5V to 5.5V input range. Consider the 8-UFDFN package constraints for PCB layout. Evaluate thermal performance within the specified -40°C to 85°C operational window.

Part Context

This part belongs to the A8735 series from Allegro MicroSystems, categorized under specialized power management ICs. It is distinct from other Allegro sensors like the A1335 angle sensor or motor drivers like the A4935. The series focuses on specific photoflash energy storage management rather than general power conversion or sensing.
