ADPL62083UR29H+T

Supervisors Overview

The ADPL62083UR29H+T is a low-power supervisory circuit manufactured by Analog Devices Inc. It monitors supply voltages ranging from 1.02V to 4.8V using a factory-set reset threshold of 2.927V. The device operates within an extended temperature range of -40°C to 125°C and is housed in a compact 3-lead SOT-23 package. It features an open-drain or open-collector active-low reset output, ensuring reliable system supervision for voltage monitoring applications.

Supervisors Feature Summary

• Monitors supply voltages from 1.02V to 4.8V with a fixed factory-set reset threshold
• Features an open-drain or open-collector active-low reset output signal
• Operates across an extended industrial temperature range of -40°C to 125°C

Supervisors Applications

• Portable battery-powered equipment requiring voltage supervision
• Wireless communication systems needing power management oversight
• Industrial control systems utilizing microcontroller reset monitoring

Supervisors Procurement Notes

Verify the specific suffix UR29H confirms the 2.927V threshold setting before procurement. Ensure the SOT-23-3 package variant matches the target PCB footprint requirements. Confirm that the open-drain output configuration aligns with the downstream logic interface voltage levels. Check for RoHS compliance status indicated by the +T designation in ordering information.

Supervisors Selection Notes

Select this component when a fixed threshold near 2.9V is required for 3.3V or similar rail monitoring. The low quiescent current makes it suitable for energy-constrained designs. Consider the open-drain output capability if level shifting or wired-OR configurations are necessary. Verify that the input voltage range covers the minimum operating voltage of the monitored system.

Supervisors Part Context

This part belongs to the ADPL62083 family of low-power supervisors. The family offers various factory-set thresholds to accommodate different voltage rails. The ADPL62083 series is designed for space-constrained applications, utilizing the small SOT-23 package. It provides essential reset functionality for digital circuits without requiring external components for threshold setting.

Supervisors Replacement Considerations

Direct substitutes within the same family include other ADPL62083 variants with different threshold suffixes. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers. Ensure replacement parts support the same -40°C to 125°C temperature range and SOT-23-3 package.
