MAX709MCPA+

Supervisors Overview

The MAX709MCPA+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 4.4V. The device provides a single monitored input with an active-low, push-pull/totem-pole output. It includes manual reset functionality and offers a minimum reset timeout delay of 140ms. The component supports through-hole mounting in an 8-DIP package and functions as a simple reset or power-on reset supervisor without watchdog timer capabilities.

Supervisors Feature Summary

• Provides hardware-based supervision for microprocessors via a fixed 4.4V threshold
• Features manual reset capability allowing user-initiated system restarts
• Delivers active-low reset signals using a push-pull output structure

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Electronic equipment power supervision

Supervisors Procurement Notes

Verify the specific suffix 'M' indicates the 4.4V threshold variant when sourcing replacements. Confirm the 'C' designation corresponds to the commercial temperature grade requirements for your application environment. Ensure the 'PA+' suffix aligns with lead-free and RoHS compliance standards mandated by your manufacturing regulations. Cross-reference the 8-DIP package dimensions against your PCB footprint specifications to guarantee mechanical compatibility during assembly.

Supervisors Selection Notes

Select this component when a fixed 4.4V reset threshold is required for standard logic systems. Choose the through-hole DIP package if prototyping or high-reliability manual insertion is preferred over surface mount alternatives. Consider the manual reset feature if external user intervention for system recovery is necessary. Evaluate the 140ms minimum timeout duration against the startup requirements of the target microprocessor to ensure stable initialization.

Supervisors Part Context

This part belongs to the MAX709 series of voltage supervisors designed for low-cost, reliable operation. It serves as a fundamental building block for ensuring system stability by detecting under-voltage conditions. The Maxim Integrated lineage emphasizes robust performance in consumer and industrial electronics where consistent power management is critical for preventing data corruption or hardware faults.
