MAX6423US26+

Supervisors Overview

The MAX6423US26+T is a low-power supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 2.625 V with an accuracy of 1.5%. The device provides an active-low, open-drain output and includes a capacitor-adjustable reset timeout delay of 4.375 ms. It consumes only 2.5 uA of quiescent current and functions reliably across a temperature range of -40°C to +125°C. Packaged in a compact SC-70-4 or SOT-143-4 surface-mount format, it lacks manual reset, watchdog timer, and battery backup switch capabilities.

Supervisors Feature Summary

• Capacitor-adjustable reset timeout delay for customizable timing requirements
• Ultra-low power consumption suitable for battery-operated systems
• Compact surface-mount packaging for space-constrained designs

Supervisors Applications

• Portable consumer electronics requiring low standby current
• Battery-powered instrumentation and measurement devices
• Microprocessor system supervision in embedded applications

Supervisors Procurement Notes

Verify the specific suffix (e.g., XS26 vs US26) against the official datasheet to ensure correct package type and electrical characteristics. Confirm RoHS compliance status through manufacturer documentation. Check availability as distribution channels may list limited stock or end-of-life statuses. Ensure the selected variant matches the required threshold voltage and operating temperature range for the target application environment.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with adjustable timeout is required. Compare against similar parts like the MAX6461 if different package options are needed. Consider the 2.625 V threshold suitability for 3.3 V logic systems. Evaluate the SC-70/SOT-143 footprint constraints against PCB layout requirements. Verify that the absence of a manual reset pin aligns with the system design strategy.

Supervisors Part Context

This part belongs to the MAX6423 series of microprocessor reset circuits designed for low-power applications. It complements other Maxim Integrated supervisory solutions by offering capacitor-adjustable delays in small packages. The series supports various threshold voltages to accommodate different rail monitoring needs in portable and industrial equipment.
