ADM705ANZ

Supervisors Overview

The ADM705ANZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range of 4.75 V to 5.5 V and features a threshold voltage of 4.65 V. The device includes a watchdog timer, manual reset capability, and power-fail detection. It provides a push-pull output with a reset delay time of 200 ms. The component is housed in an 8-PDIP package for through-hole mounting and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability monitoring
• Manual reset input allowing user-initiated system recovery
• Power-fail detection circuitry for voltage supervision
• Push-pull output configuration for robust signal driving

Supervisors Applications

• Microprocessor reset generation in embedded systems
• Voltage supervision for single-input power rails
• Watchdog timer implementation in industrial controllers
• Manual reset integration in safety-critical hardware

Supervisors Procurement Notes

Verify the specific suffix 'ANZ' to confirm the lead-free and RoHS-compliant variant. Ensure the ordering code matches the PDIP-8 through-hole package requirements. Confirm that the 4.65 V threshold aligns with the target system's voltage specifications before procurement.

Supervisors Selection Notes

Select this component when a dedicated voltage supervisor with integrated watchdog and manual reset is required. The 8-PDIP package suits through-hole designs. Verify that the 200 ms reset delay meets the timing constraints of the monitored microprocessor or logic circuit during power-up sequences.

Supervisors Part Context

This part belongs to the ADM705 series of low-cost microprocessor supervisory circuits. It serves as a direct replacement for the obsolete ADM705AN model. The series is categorized under PMIC voltage supervisors, providing essential protection against brown-out conditions and software faults in digital systems.

Supervisors Replacement Considerations

The ADM705ANZ is the direct replacement for the discontinued ADM705AN. Cross-referencing with MAX705 variants may require verification of pin compatibility and threshold voltage tolerances.
