DS1706LEUA

Supervisors Overview

The DS1706LEUA+ is a MicroMonitor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 1.2 V to 5.5 V and features a UMAX-8 package. The device monitors a single input with thresholds at 3.3 V and 5.0 V, providing an active low push-pull output. Key specifications include a reset delay time of 285 ms, a watchdog timer function, manual reset capability, and no battery backup switch. It draws 60 uA during operation and detects power failures. The component supports an operating temperature range from -40 C to +85 C.

Supervisors Feature Summary

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

Supervisors Applications

• Voltage supervision in embedded systems
• Microprocessor reset management
• Power integrity monitoring in portable devices

Supervisors Procurement Notes

Verify the specific suffix requirements for your design, as the LEUA variant denotes a particular package type. Confirm that the manual reset feature aligns with your system architecture, distinguishing it from variants without this input. Check current availability status, as lifecycle changes may affect sourcing options for this discontinued or limited-stock component.

Supervisors Selection Notes

Choose the DS1706LEUA+ when a manual reset input is required alongside standard voltage supervision. Its UMAX-8 package suits space-constrained designs compared to larger DIP options. Ensure the 285 ms reset delay meets your timing constraints, as other family members offer different delays like 205 ms. Verify compatibility with your target voltage levels against alternative threshold configurations.

Supervisors Part Context

This component belongs to the DS1706L series of MicroMonitor circuits. It shares functional similarities with other DS1706 variants but differs in package style and specific features like the manual reset pin. The LEUA designation specifically identifies the ultra-miniature package option within the broader supervisory circuit portfolio offered by the manufacturer.
