MAX6706ASKA+T

Supervisors Overview

The MAX6706ASKA+T is a low-voltage microprocessor supervisor circuit manufactured by Analog Devices Inc. (formerly Maxim Integrated). It monitors a single voltage input and provides reset, watchdog, and power-fail functions in an SOT-23-8 package. The device operates with a supply voltage range up to 5.5V and features a manual reset input. Key electrical parameters include a threshold voltage of 2.93V, a reset delay time of 140ms minimum, and a power-fail threshold of 4.5V. It draws 12µA of operating current and supports an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates multiple supervisory functions including reset output, watchdog timer, and power-fail detection within a single compact component.
• Features a manual reset input allowing for external control over the system reset state independent of voltage monitoring.
• Provides active-high push-pull reset output suitable for direct interfacing with various logic families without additional pull-up components.

Supervisors Applications

• Microcontroller power supply monitoring
• Embedded system brownout protection
• Watchdog timer implementation for system reliability

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or Analog Devices directly due to discontinued status. Confirm RoHS compliance and lead-free specifications as indicated in official documentation. Check for potential obsolescence notices or last-time buy information via manufacturer channels before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset capability is required. Ensure the 2.93V threshold aligns with the monitored rail voltage. Consider the SOT-23-8 package constraints for PCB layout. Verify that the 12µA quiescent current meets system power budget requirements compared to higher-current alternatives.

Supervisors Part Context

Part of the MAX6701-MAX6708 family of low-voltage supervisors designed to simplify microprocessor system design. These circuits replace discrete components by integrating reset, watchdog, and power-fail functions. The MAX6706 variant specifically offers adjustable thresholds and manual reset inputs, enhancing flexibility in complex power management scenarios.
