DS1706SEPA

Supervisors Overview

The DS1706SEPA is a MicroMonitor 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 features a fixed threshold voltage of 3.3 V for power monitoring. The device provides an active-low, push-pull output with a reset delay time of 205 ms. It includes a built-in watchdog timer and power-fail detection capabilities but lacks manual reset or battery backup switching functions. The component is housed in an 8-PDIP package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Power-fail warning detection capability
• Active-low push-pull output configuration

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-operated systems monitoring

Supervisors Procurement Notes

Verify the specific suffix 'SEPA' against official datasheets to confirm the 8-PDIP package and 3.3V threshold. Confirm RoHS compliance status as legacy parts may vary. Check current availability through authorized distributors, as this model may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.3V threshold is required for single-input voltage monitoring. The inclusion of a watchdog timer makes it suitable for applications needing automated recovery from software hangs. Consider the PDIP package for through-hole mounting requirements. Verify that the 205 ms reset delay meets the timing specifications of the target microprocessor.

Supervisors Part Context

The DS1706SEPA belongs to the Maxim Integrated MicroMonitor family, designed for simple voltage supervision tasks. It is part of the DS1706 series, which offers various threshold voltages and package options. This specific variant utilizes the standard DIP-8 form factor, distinguishing it from surface-mount equivalents like the SESA or SEUA models within the same product line.

Supervisors Replacement Considerations

Direct replacements include other variants within the DS1706 series such as DS1706PEPA+ or DS1706PESA+, depending on package preference. Cross-brand alternatives like the TPS3705-33DGN may offer similar functionality but require verification of pinout and electrical parameters.
