PT7M7823STAEX

Supervisors Overview

The PT7M7823STAEX is a microprocessor supervisory circuit manufactured by Diodes Incorporated, designed to enhance power supply reliability in embedded systems. It features a precision voltage monitor with a threshold of 2.63V and a fixed 200ms reset pulse width. The device provides an open-drain reset output signal suitable for watchdog and manual reset applications. It operates within a temperature range of -40°C to +85°C and guarantees valid reset states down to a supply voltage of 1.0V.

Supervisors Feature Summary

• Precision supply-voltage monitoring with defined threshold levels
• Fixed 200ms reset pulse width for stable system initialization
• Open-drain reset output compatible with CMOS logic interfaces

Supervisors Applications

• Microprocessor system power supervision
• Watchdog timer integration
• Manual reset input circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to potential availability constraints. Confirm package integrity and pin alignment against the official datasheet specifications prior to assembly. Ensure storage conditions comply with moisture sensitivity level requirements to maintain device performance and prevent soldering defects during surface mount processing.

Supervisors Selection Notes

Select this component when an open-drain reset output is required for interfacing with specific logic families or pull-up configurations. The 2.63V threshold suits applications monitoring lower voltage rails compared to standard 3.3V or 5V monitors. Consider the 200ms delay duration relative to system startup timing requirements to ensure adequate stabilization before processor execution begins.

Supervisors Part Context

This part belongs to the PT7M78xx family of µP supervisor circuits from Diodes Incorporated. The family targets improved reliability in microprocessor systems by reducing component count and complexity associated with power monitoring. Variants differ primarily in threshold voltage and output configuration, such as push-pull versus open-drain outputs.

Supervisors Replacement Considerations

Check for direct substitutes within the PT7M78xx series that match the 2.63V threshold and open-drain output requirement. Verify pin compatibility and electrical characteristics against the original specification sheet before implementing any alternative components.
