MAX6808XR26

Supervisors Overview

The MAX6808XR26 is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single voltage inputs. It operates within a supply voltage range of 1 V to 5.5 V and features an active-low open-drain output. The device provides a fixed threshold voltage of 4.6 V with 2% accuracy. It includes a standard reset timeout of 30 µs and lacks manual reset or watchdog timer functions. The component supports surface-mount installation in SC-70-3 packages and operates across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simple reset or power-on-reset functionality for monitored voltage rails
• Features an active-low open-drain output interface compatible with various logic families
• Operates without requiring external components such as resistors or capacitors

Supervisors Applications

• Embedded system power supply supervision
• Microcontroller reset circuitry
• Portable electronic device voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix 'R26' against official datasheets to confirm the 4.6 V threshold and SC-70-3 package configuration. Confirm RoHS compliance status through manufacturer documentation. Check current lifecycle status as distribution channels may list this part as obsolete or limited supply. Ensure pinout compatibility with target PCB footprint before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-channel voltage monitoring. Consider the SC-70-3 package size constraints and the absence of manual reset capabilities. Evaluate if the 30 µs reset timeout meets system timing requirements. Compare against other MAX6808 variants if different thresholds or packages are needed.

Supervisors Part Context

The MAX6808 series belongs to Maxim Integrated's line of ultra-small, low-power voltage supervisors. These devices are engineered for applications where board space and power consumption are critical. The XR26 variant specifically denotes the 4.6 V threshold version housed in the compact SC-70-3 package, targeting portable and space-constrained designs.
