DS1708REUA

Supervisors Overview

The DS1708REUA+ is a MicroMonitor voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.32V to 5.5V and features a fixed threshold voltage of 4.65V for monitoring power rails. The device provides a push-pull output that can be configured as active high or active low, with a typical reset delay time of 205ms. It functions without a manual reset input or watchdog timer and includes power-fail detection capabilities. The component is housed in an 8-UMAX package and supports surface-mount installation.

Supervisors Feature Summary

• Monitors single voltage input with fixed threshold
• Configurable active high/low push-pull output
• Includes power-fail warning detection

Supervisors Applications

• Portable equipment power management
• Battery-powered system supervision
• Microprocessor reset circuits

Supervisors Procurement Notes

Verify the specific suffix REUA against official datasheets to confirm the 8-UMAX package type and pinout configuration. Ensure the required threshold voltage matches the design specifications before procurement. Confirm RoHS compliance status through manufacturer documentation. Check current availability as distribution may vary.

Supervisors Selection Notes

Select this component when a fixed 4.65V threshold is required for system supervision. Consider the 205ms reset delay for timing constraints. Verify compatibility with the target operating temperature range of -40°C to +85°C. Ensure the push-pull output drive capability meets load requirements.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor family of voltage supervisors. These devices are designed for low-power applications requiring reliable power management. The series offers various threshold options and package configurations to suit different embedded system needs.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same MicroMonitor family with adjusted thresholds. Verify functional equivalence regarding output polarity and reset delay times.
