DS1232LPS-2+T&R

Supervisors Overview

The DS1232LPS-2+T&R is a low-power MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V and features a single monitored input with an accuracy of 10%. The device includes an integrated watchdog timer and provides power-fail detection capabilities. Reset delay time is specified at 610 ms, while the overvoltage threshold varies by variant, reaching up to 5.5 V in some configurations. Operating temperatures span from 0°C to +70°C for commercial variants. The component utilizes SOIC-8 surface-mount packaging and offers active high, active low, or open drain output types without manual reset functionality.

Supervisors Feature Summary

• Integrates a watchdog timer for system stability monitoring
• Provides power-fail detection for voltage supervision
• Supports multiple output logic states including open drain

Supervisors Applications

• Microprocessor system supervision
• Power management circuit monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix designation to confirm package type and temperature range, as variations exist within the series. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required operating temperature range and supply voltage thresholds for the target application environment.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with watchdog functionality is required. Consider the SOIC-8 package constraints for board space. Evaluate the 610 ms reset delay against system startup timing requirements. Verify that the 10% accuracy meets the precision needs of the monitored rail.

Supervisors Part Context

This part belongs to the DS1232LPS family of low-power supervisory circuits. It is designed for applications requiring reliable reset generation and power monitoring in microprocessor-based systems.
