DS1706LEUA+

Supervisors Overview

The DS1706LEUA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2 V to 5.5 V and consumes 60 uA of quiescent current. The device features an active low, push-pull output and includes a manual reset input alongside a watchdog timer. It monitors a single input with thresholds set at 3.3 V and 5.0 V, providing a reset delay of 285 ms. An overvoltage threshold of 4.75 V is supported for power failure detection. The component functions reliably across an operating temperature range from -40 C to +85 C and is housed in an UMAX-8 package.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Includes a manual reset input for user-initiated control
• Provides power failure detection capabilities
• Features an active low push-pull output structure

Supervisors Applications

• Embedded systems requiring voltage supervision
• Portable electronics with battery backup constraints
• Industrial control units needing watchdog functionality
• Communication equipment power management

Supervisors Procurement Notes

Verify the specific suffix LEUA against the official datasheet to confirm the UMAX-8 package and threshold settings. Confirm RoHS compliance status through manufacturer documentation. Check for obsolescence notices as the lifecycle status indicates discontinuation. Ensure compatibility with existing PCB footprints for the specified package type before procurement.

Supervisors Selection Notes

Select this component when a single-supervisory channel with integrated watchdog and manual reset is required. The low quiescent current makes it suitable for power-sensitive designs. Verify that the 3.3 V and 5.0 V thresholds align with the target system voltages. Consider the UMAX-8 package dimensions for space-constrained applications.
