APX803L20-25W5-7

Supervisors Overview

The APX803L20-25W5-7 is a microprocessor supervisory circuit manufactured by Diodes Incorporated. It functions as a voltage detector with a fixed threshold of 2.5V and an active low open-drain output. The device operates within a supply voltage range up to 5.5V and features a typical reset delay time of 143ms. Designed for low power consumption, it draws approximately 1µA of supply current. The component is housed in a SOT-25 surface-mount package and is rated for operation across an extended temperature range.

Supervisors Feature Summary

• Provides reliable system reset generation by monitoring power supply voltage levels against a fixed internal threshold.
• Features an active low open-drain output interface suitable for direct connection to microprocessor reset pins.
• Designed for ultra-low quiescent current consumption to preserve battery life in portable applications.

Supervisors Applications

• Microprocessor supervisory circuits
• Battery-powered digital systems
• Portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix W5-7 against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure compliance with RoHS directives and check for any recent product discontinuation notifications prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.5V detection threshold is required for system supervision. The SOT-25 package offers space efficiency compared to standard SOT-23 variants. Consider the 143ms reset delay duration to ensure compatibility with the target microprocessor's startup timing requirements. Verify that the active low output polarity matches the design logic.

Supervisors Part Context

This part belongs to the APX803L series of micropower voltage detectors developed for microprocessor applications. The series provides various fixed detection voltage options ranging from 1.2V to 5.0V. The APX803L20-25W5-7 specifically utilizes the 2.5V threshold variant within the W5 package configuration, distinguishing it from other pinout or threshold versions in the family.
