DS1707ESA/T&R

Supervisors Overview

The DS1707ESA+T&R is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed as a MicroMonitor for 3.3V and 5.0V systems. It operates within a supply voltage range of up to 5.5V with a typical operating current of 60µA. The device features a reset delay time of 205ms and an accuracy of 5%. It supports active high, active low, and push-pull output types. The component is housed in an SOIC-8 package and functions without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Monitors power supply voltages at 3.3V and 5.0V levels
• Provides configurable reset outputs including active high, active low, and push-pull configurations
• Detects power failures to ensure system integrity

Supervisors Applications

• Portable equipment requiring voltage supervision
• Battery-powered consumer electronics
• Industrial control systems monitoring 5V logic supplies

Supervisors Procurement Notes

Verify the specific suffix designation when ordering, as tape-and-reel packaging may differ from tube quantities. Confirm RoHS compliance status through official documentation prior to integration. Check for obsolescence notices or lifecycle changes directly from the manufacturer. Ensure the selected variant matches the required output configuration and package type for your PCB layout.

Supervisors Selection Notes

Select this component when a single-input voltage monitor is needed for standard 5V or 3.3V rails. Consider the 60µA quiescent current for battery-sensitive designs. Evaluate the 205ms reset delay against system startup requirements. Verify that the SOIC-8 package fits the available board space and thermal constraints.

Supervisors Part Context

This part belongs to the DS1707 series of MicroMonitors, which are dedicated supervisory circuits. These devices are engineered to provide reliable reset signals for microprocessors and memory systems. The series typically offers various output options and threshold voltages to accommodate different logic families and power architectures.
