DS1708TESA

Supervisors Overview

The DS1708TESA+ is a MicroMonitor voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features a fixed threshold voltage of 3.3 V with 5% accuracy. The device provides power-fail detection and includes a reset delay time of 205 ms. It supports active high, active low, and push-pull output types without manual reset or watchdog timer functions. Designed for surface-mount installation in an SOIC-8 package, it operates reliably across a temperature range of -40°C to +85°C while consuming 60 µA of working current.

Supervisors Feature Summary

• Provides precise monitoring of single-input power supply voltages with configurable output polarity options.
• Integrates power-fail detection capabilities alongside standard reset generation functions.
• Features a dedicated reset delay mechanism to ensure stable system initialization upon power-up.

Supervisors Applications

• Monitoring 3.3 V logic supply rails in embedded systems
• Supervising 5.0 V power inputs in industrial control units
• Ensuring reliable startup sequences in microprocessor-based circuits

Supervisors Procurement Notes

Verify the exact suffix designation against official datasheets, as variations may indicate different packaging or temperature grades. Confirm RoHS compliance status through manufacturer documentation prior to integration. Ensure the selected variant matches the required output configuration and package type for your specific PCB layout constraints.

Supervisors Selection Notes

Select this component when a single-channel voltage supervision function is required for 3.3 V or 5.0 V systems. Consider the specific output drive requirements, such as push-pull versus open-drain, to match downstream logic interfaces. Evaluate the thermal operating range to ensure suitability for the intended environmental conditions.

Supervisors Part Context
