DS1706LESA/T&R

Supervisors Overview

The DS1706LESA/T&R is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2 V to 5.5 V and monitors a single input channel with a threshold voltage of 3.3 V. The device features an active low, push-pull output and includes a manual reset function alongside a watchdog timer. It provides power-fail detection and has a reset delay time of 285 ms. The component is housed in an SOIC-Narrow-8 package and supports surface mount installation. It functions across a temperature range of -40°C to +85°C with a typical operating current of 60 µA.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides manual reset capability for user-initiated control
• Detects power failures via dedicated power-fail output
• Offers active low push-pull output configuration

Supervisors Applications

• Embedded systems requiring voltage supervision
• Microprocessor reset circuits
• Portable electronic devices with battery backup
• Industrial control systems needing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix T&R indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as availability may vary. Check for obsolescence notices since this part series has faced discontinuation trends. Ensure the SOIC-8 footprint matches your PCB design constraints before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset and watchdog features is required. Compare threshold accuracy and reset delay times against other DS1706 variants if precise timing is critical. Consider the SOIC-8 package size relative to available board space. Verify that the 3.3 V threshold aligns with the monitored rail voltage requirements.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family, designed for simple voltage supervision tasks. The DS1706 series typically combines power-on reset, manual reset, and watchdog timer functions in a compact package. Variants differ primarily in threshold voltages, package types, and reset polarity configurations.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the DS1706 series such as DS1706REPA+ or DS1706SESA+ depending on threshold and package needs. Verify functional equivalence regarding watchdog timeout periods and reset delays.
