APX803S05-40SR-7

Supervisors Overview

The APX803S05-40SR-7 is a single-channel voltage monitor manufactured by Diodes Incorporated, designed to supervise power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4 V. The device provides an active low, push-pull output with a reset delay time of 50 ms. It supports surface mount installation in an SOT-23-3 package and functions reliably across a temperature range from -40 °C to +125 °C.

Supervisors Feature Summary

• Provides active low push-pull output for direct logic interfacing
• Operates over extended industrial temperature ranges up to 125 °C
• Features a fixed 50 ms reset delay for stable power-up sequencing

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring in embedded controllers
• Industrial control unit reset generation

Supervisors Procurement Notes

Verify the specific suffix SR-7 against official Diodes Incorporated documentation to confirm package type and tape-and-reel specifications. Ensure the 4 V threshold aligns with target circuit requirements. Confirm RoHS compliance status through current datasheets before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a push-pull output is required instead of open-drain configurations. The 4 V threshold suits applications monitoring higher voltage rails. Verify that the 50 ms delay meets system timing constraints. Consider thermal performance limits when designing for high ambient temperatures.

Supervisors Part Context

This part belongs to the APX803S series of microprocessor supervisors. It shares family characteristics with other variants differing primarily in threshold voltage and output stage configuration. The series focuses on compact SOT-23-3 packaging for space-constrained designs.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the APX803S family. Verify if open-drain outputs are acceptable substitutes. Confirm electrical parameter equivalence before swapping components.
