MAX706TEUA+

Supervisors Overview

The MAX706TEUA+ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an 8-pin UMAX surface-mount package. It monitors a single voltage input with a threshold of 3.08 V and an overvoltage threshold of 3.15 V. The device features an active low push-pull output, manual reset capability, and an integrated watchdog timer. It operates within a supply voltage range up to 5.5 V, consumes 135 uA of quiescent current, and maintains accuracy within 2.5%. The reset delay time is 200 ms, and it supports power-fail detection. The component functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset input for user-initiated control
• Detects power failures with active low push-pull output signaling

Supervisors Applications

• Desktop computer systems
• Portable computers and laptops
• Test and measurement instruments
• Battery-powered portable devices
• Multi-output power supplies

Supervisors Procurement Notes

Verify the specific suffix TEUA against the target design requirements to ensure compatibility with the UMAX-8 package and the 3.08 V threshold voltage. Confirm that the manufacturer's datasheet specifications align with the application's electrical constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a low-cost supervisory circuit with integrated watchdog functionality is required for single-input voltage monitoring. Ensure the design accommodates the UMAX-8 surface-mount footprint and operates within the specified -40°C to +85°C temperature range while utilizing the manual reset feature.

Supervisors Part Context

This part belongs to the MAX706 series of microprocessor power-supply supervisors. These circuits are designed to monitor voltage levels and provide reset signals to protect digital systems from power-related faults. The MAX706TEUA+ variant specifically targets applications requiring compact surface-mount packaging and precise voltage supervision.

Supervisors Replacement Considerations

Cross-reference with other MAX706 variants such as MAX706ASESA+ or MAX706ATEPA+ if different packages or threshold voltages are needed. Verify pinout compatibility and functional equivalence before substituting.
