APX809S00-31SR-7

Supervisors Overview

The APX809S00-31SR-7 is a voltage monitor and reset generator manufactured by Diodes Incorporated. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 3.08 V. The device provides an active low, push-pull output with a reset delay time of 240 ms. It is housed in a SOT-23-3 package and supports surface mount installation. The component functions without manual reset, watchdog timer, or battery backup switch capabilities. It is rated for operation between -40°C and +125°C.

Supervisors Feature Summary

• Provides automatic system reset generation upon detection of under-voltage conditions relative to the specified threshold.
• Delivers a stable logic-level output signal through a push-pull configuration without requiring external components.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered device voltage supervision
• Embedded system reset circuitry

Supervisors Procurement Notes

Verify the specific suffix SR-7 corresponds to the required reel packaging format from the manufacturer's official documentation. Confirm that the 3.08 V threshold aligns with the target application's voltage requirements. Ensure compatibility with the SOT-23-3 footprint during PCB layout validation. Cross-reference the part number against current Diodes Incorporated datasheets to confirm active status and electrical specifications before procurement.

Supervisors Selection Notes

Select this component when a low quiescent current voltage monitor with a fixed 3.08 V threshold is required. The SOT-23-3 package suits space-constrained designs. Consider the 240 ms reset delay duration to ensure it meets the microcontroller startup timing requirements. Verify that the active low output polarity matches the target system's reset input logic.

Supervisors Part Context

This part belongs to the APX809S series of supervisory circuits from Diodes Incorporated. The series offers various threshold voltages and output polarities within the same SOT-23-3 form factor. The APX809S variants typically feature active low outputs, distinguishing them from the APX810S series which offers active high options.
