MAX823REXK+T

Supervisors Overview

The MAX823REXK+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage input with a threshold of 2.63 V and an overvoltage threshold of 2.66 V. The device features an active low, push-pull output and provides a manual reset function alongside a watchdog timer. The reset delay time is specified at 200 ms. Operating within a supply voltage range up to 5.5 V, it draws 4 uA of quiescent current. The component is housed in a SC-70-5 package and supports surface mount installation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a manual reset input for user-initiated control
• Provides active low push-pull output for direct logic interfacing

Supervisors Applications

• Microprocessor supervisory circuits
• Voltage monitoring in embedded systems
• System reset management in portable devices

Supervisors Procurement Notes

Verify the specific suffix EXK+T against the manufacturer's official datasheet to confirm pinout compatibility and electrical characteristics. Ensure the SC-70-5 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 2.63 V threshold is appropriate for the monitored rail. Consider the 200 ms reset delay and 4 uA current consumption relative to system power budgets. Evaluate the need for manual reset and watchdog functionality versus simpler supervisor options. Verify that the SC-70-5 package fits the available board space constraints.

Supervisors Part Context

This part belongs to the MAX823 series of microprocessor supervisors from Maxim Integrated. The series offers various threshold voltages and package options to suit different low-voltage system requirements. The MAX823REXK+T specifically targets applications requiring precise voltage monitoring with integrated watchdog capabilities in a compact form factor.

Supervisors Replacement Considerations

MAX823YEXK+T (2.19V threshold), MAX823LEXK+T (4.63V threshold). Verify threshold voltage compatibility before substitution.
