ADM706TANZ

Supervisors Overview

The ADM706TANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supplies and battery levels. 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 and a debounced manual reset input. It operates within a supply voltage range up to 5.5 V and maintains a low quiescent current of 190 μA. The component supports active high reset output and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates an independent watchdog timer with a fixed 1.60-second timeout interval for system reliability.
• Provides a debounced TTL/CMOS compatible manual reset input (MR) for user-initiated control.
• Delivers a guaranteed valid RESET signal when the supply voltage drops as low as 1 V.
• Features a precision supply voltage monitor calibrated at 4.40 V for accurate power supervision.

Supervisors Applications

• Microprocessor systems requiring critical power supply monitoring
• Computers and controllers needing reliable reset generation
• Intelligent instruments with battery backup requirements

Supervisors Procurement Notes

Verify the specific suffix 'AN' indicates the PDIP-8 through-hole package variant. Confirm RoHS compliance status directly from the manufacturer datasheet, as legacy stock may vary. Check availability constraints, as this part number may be subject to limited supply or end-of-life conditions depending on the distribution channel. Ensure the active high output configuration matches the target design requirements.

Supervisors Selection Notes

Select the ADM706TANZ when a 4.40 V threshold and active high reset output are required. This variant is suitable for designs utilizing through-hole mounting in PDIP-8 packages. Compare against the ADM706RANZ if surface-mount SOIC packaging is preferred instead. Verify that the 190 μA quiescent current meets the system's power budget constraints during normal operation.

Supervisors Part Context

The ADM706TANZ belongs to the ADM705/ADM706/ADM707/ADM708 family of low-cost microprocessor supervisory circuits. These devices are engineered to monitor 5 V power supplies and batteries while also tracking microprocessor activity. The family offers variations in reset polarity and packaging, providing flexibility for different embedded system architectures and manufacturing needs.
