DS1706LESA+

Supervisors Overview

The DS1706LESA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in an SOIC-8 surface-mount package. It features a threshold voltage of 3.3 V and supports a maximum supply voltage of 5.5 V with a minimum operating voltage of 1.2 V. The device includes a watchdog timer and power-fail detection but lacks manual reset and backup switch capabilities. It operates within a temperature range of -40°C to +85°C, draws 60 uA of working current, and provides an active low push-pull output with a reset delay time of 285 ms.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Power-fail detection capability for voltage supervision
• Active low push-pull output interface

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in embedded systems
• Watchdog timer implementation in industrial control

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific manufacturing lot codes against official datasheets before integration. Ensure that the SOIC-8 package dimensions match PCB footprint requirements precisely. Cross-reference part numbers carefully as similar variants exist within the DS1706L series with different accuracy levels.

Supervisors Selection Notes

Select this component when a fixed 3.3 V threshold with high accuracy is required alongside integrated watchdog functionality. Compare against other DS1706 variants based on accuracy specifications such as 5% or 10% tolerance if precision differs from the L-series standard. Consider the absence of manual reset and backup switches when designing user interaction or battery-backed memory circuits.

Supervisors Part Context

This part belongs to the DS1706L MicroMonitor family designed for voltage supervision and system reset management. It complements other devices like the MAX817 and MAX808 series which offer similar supervisory functions but may differ in output types, reset delays, or additional features like chip enable signals.

Supervisors Replacement Considerations

DS1706SESA+ offers 10% accuracy; DS1706TESA+ offers 5% accuracy. Both share similar functional blocks but differ in threshold precision.
