APX810S00-40SA-7

Supervisors Overview

The APX810S00-40SA-7 is a voltage monitor manufactured by Diodes Incorporated, designed for supervising power supply rails 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 high, push-pull output signal with a reset delay time of 1.7 ms. It is housed in a SOT-23-3 package and supports surface mount installation. The component functions across a temperature range from -40°C to +125°C, ensuring reliable performance in demanding environments.

Supervisors Feature Summary

• Provides active high push-pull output for direct logic interface compatibility
• Features a fixed 4 V threshold voltage for precise power rail supervision
• Operates over an extended industrial temperature range up to +125°C

Supervisors Applications

• Microprocessor (MPU) power voltage detection
• Battery backup switching circuits
• General purpose power supply monitoring

Supervisors Procurement Notes

Verify the specific suffix 'SA' indicates the correct pinout and tolerance configuration required for your design. Confirm that the active high output polarity aligns with your system's reset logic requirements. Ensure the 1.7 ms delay meets the timing constraints of the monitored circuit during power-up sequences. Cross-reference the datasheet for absolute maximum ratings to prevent overstress conditions.

Supervisors Selection Notes

Select this component when an active high output is required for the reset signal, distinguishing it from the APX809 series which offers active low outputs. The 4 V threshold is suitable for 3.3 V or 5 V systems requiring early detection of undervoltage conditions. Consider the 1.7 ms delay relative to other variants like the APX810S-44SR-7 which has a significantly longer 240 ms delay. Evaluate the SOT-23-3 footprint against available PCB space constraints.

Supervisors Part Context

This part belongs to the APX810S series of voltage monitors from Diodes Incorporated. It is functionally similar to the APX809S series but differs in output polarity, providing an active high signal instead of active low. The series includes various threshold voltages and packaging options to support diverse application needs. It serves as a dedicated supervisor IC for maintaining system stability during power transitions.
