APX810S-23SR-7

Supervisors Overview

The APX810S-23SR-7 is a single-channel voltage monitor manufactured by Diodes Incorporated, designed for MPU power supervision. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 2.25 V. The device provides an active high, push-pull output with a reset delay time of 1.7 ms. It lacks manual reset, watchdog timer, or battery backup switch functions. The component supports surface mount installation in an SOT-23-3 package and functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides active high push-pull output for reliable signal interfacing
• Operates over extended industrial temperature range from -40°C to +125°C
• Features low quiescent current consumption for power efficiency

Supervisors Applications

• MPU power voltage detection
• Embedded system reset generation
• Portable electronic device supervision

Supervisors Procurement Notes

Verify the specific suffix SR-7 corresponds to the required tape and reel packaging configuration when ordering. Confirm that the active high output polarity matches the target circuit design requirements. Ensure the 2.25 V threshold aligns with the monitored rail's nominal voltage level. Check RoHS compliance status against project specifications before finalizing procurement.

Supervisors Selection Notes

Select this component when an active high output is required for the supervisory circuit. The 1.7 ms reset delay suits applications needing rapid recovery after power restoration. Consider the SOT-23-3 package for space-constrained PCB layouts. Verify compatibility with the system's maximum operating voltage of 5.5 V. Evaluate thermal performance needs given the wide operating temperature range.

Supervisors Part Context

This part belongs to the APX810S series of simple reset circuits from Diodes Incorporated. It shares the family's core architecture but differs in output polarity and threshold settings compared to variants like the APX809S series. The series targets cost-sensitive embedded applications requiring basic power monitoring without complex timing features.

Supervisors Replacement Considerations

APX810S05-23SR-7 serves as a parameter-equivalent alternative within the same manufacturer lineup.
