DS1706ESA+

Supervisors Overview

The DS1706ESA+ is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring power supply voltages in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 5 V with an accuracy of 10%. The device includes a watchdog timer and detects power failures, providing an active low push-pull output. It has a reset delay time of 205 ms and consumes a working supply current of 60 uA. The component supports a single input and functions across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Detects power failure events automatically
• Provides active low push-pull output signal
• Operates without manual reset or chip enable signals

Supervisors Applications

• Microprocessor system supervision
• Power supply voltage monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited supply or discontinuation. Confirm RoHS compliance details through official documentation. Ensure the SOIC-Narrow-8 package matches design requirements. Check for specific ordering suffixes if tape-and-reel packaging is needed instead of tube. Validate manufacturer part number against official Analog Devices databases before procurement.

Supervisors Selection Notes

Select this component when a 5 V threshold is required for supervising digital logic supplies. Consider the 10% accuracy specification for budgeting voltage margins. The 60 uA operating current suits low-power applications. Verify that the absence of manual reset meets system safety protocols. Ensure the SOIC-8 footprint fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the DS1706 series of MicroMonitor circuits from Analog Devices / Maxim Integrated. It is categorized under PMIC - Power Management ICs and specifically Supervisory Circuits. The device is distinct from variants like DS1706EPA+ due to its surface mount SOIC-8 packaging rather than through-hole PDIP-8.

Supervisors Replacement Considerations

DS1706ESA+T&R offers the same electrical specifications in tape-and-reel packaging. DS1706SESA+ provides a 3.3 V threshold variant in the same package. DS1706EPA+ is a through-hole equivalent but is marked as end-of-life.
