MAX706PESA+

Supervisors Overview

The MAX706PESA+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single-input power rails. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 2.63 V with an accuracy of 2.5%. The device includes a manual reset input, a watchdog timer, and power-fail detection capabilities. It provides a push-pull active high output with a reset delay time of 200 ms. Operating temperatures range from -40°C to +85°C, and it consumes 135 uA of working current. The component is housed in an 8-PDIP package.

Supervisors Feature Summary

• Integrates manual reset functionality alongside automatic power-on reset generation for comprehensive system control.
• Includes a built-in watchdog timer to ensure microprocessor reliability through automated timeout recovery.
• Provides dedicated power-fail detection to signal voltage anomalies before critical thresholds are reached.

Supervisors Applications

• Microprocessor system supervision
• Battery-powered equipment monitoring
• Portable instrumentation power management

Supervisors Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout compatibility and electrical characteristics. Ensure environmental compliance requirements match project specifications. Confirm availability status with authorized distributors as supply levels may vary. Cross-reference package dimensions for PCB layout accuracy.

Supervisors Selection Notes

Select this component when a single-channel supervisory circuit with manual reset capability is required. Consider the 2.63 V threshold for applications targeting standard logic levels. Evaluate the 135 uA quiescent current against battery life requirements. Verify that the PDIP-8 package fits the mechanical constraints of the design.

Supervisors Part Context

This part belongs to the MAX706 series of low-cost, precision voltage supervisors. It is designed to provide reliable reset signals for digital systems. The series typically offers various threshold options and packaging styles to suit different application needs while maintaining consistent supervisory functionality.

Supervisors Replacement Considerations

Check for MAX706 variants with different suffixes indicating alternative packages or temperature ranges. Verify functional equivalence if substituting with other supervisory ICs from the same manufacturer family.
