ADM706TAN

Supervisors Overview

The ADM706TAN is a microprocessor supervisory circuit designed for monitoring power supplies and battery systems. It features a precision voltage monitor with a threshold of 4.40 V, ensuring valid RESET signals down to VCC = 1 V. The device includes an independent watchdog timer with a 1.60-second timeout period and a debounced manual reset input. It operates within a supply voltage range up to 5.5 V and provides a push-pull active low reset output. The component is housed in an 8-SOIC package and supports operation across temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a fixed 4.40 V threshold for reliable power supervision
• Includes an independent watchdog timer with a 1.60-second timeout to detect processor activity failures
• Features a debounced manual reset input compatible with TTL/CMOS logic levels
• Provides a push-pull active low reset output that remains valid down to 1 V supply voltage

Supervisors Applications

• Microprocessor system power supervision
• Critical microprocessor supply monitoring
• Controllers and intelligent instruments
• Computers requiring low-cost supervisory solutions

Supervisors Procurement Notes

Verify the specific suffix 'TAN' against the manufacturer's current datasheet revision to confirm pinout compatibility and electrical specifications. Ensure the selected variant matches the required operating temperature range and package type for your design. Cross-reference ordering information with official Analog Devices documentation to avoid discrepancies in manufacturing revisions or regional availability constraints.

Supervisors Selection Notes

Select this component when a fixed 4.40 V threshold is appropriate for the monitored rail. The integrated watchdog timer simplifies designs requiring automatic recovery from software hangs. Consider the 8-SOIC package dimensions for PCB layout. Verify that the 1.60-second watchdog timeout aligns with the maximum allowable processing cycle time of the target microcontroller without triggering false resets.

Supervisors Part Context

The ADM706 belongs to the ADM705/ADM706/ADM707/ADM708 family of low-cost microprocessor supervisory circuits. These devices are engineered as superior upgrades for legacy MAX705-MAX708 series components. The family shares common functional blocks such as voltage monitoring and reset generation, differing primarily in threshold voltages and output polarities to suit various system architectures.

Supervisors Replacement Considerations

The MAX706ATESA+ is a confirmed substitute within the same product family. Verify that the MAX706ATESA+'s SOIC-8 package and 4.4 V threshold match the original design requirements. Check for any differences in manual reset debounce characteristics or watchdog timeout values between the ADM706 and MAX706 variants.
