Supervisors Overview

The APX803L40-13SA-7 is a micro power voltage detector manufactured by Diodes Incorporated, designed for monitoring power supplies in microprocessors and digital systems. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.0 V. The device provides an active low, open-drain output with a reset delay time of 13 ms. It is housed in a compact SOT-23-3 package and supports surface mount installation. The component functions reliably across an operating temperature range from -40°C to +85°C, ensuring stable performance in various electronic applications.

Supervisors Feature Summary

• Monitors single voltage input for system integrity
• Provides active low open-drain reset signal
• Operates with ultra-low quiescent current consumption
• Compact SOT-23-3 surface mount packaging

Supervisors Applications

• Microprocessor (μP) power supply monitoring
• Microcontroller (μC) reset generation
• Digital system voltage supervision

Supervisors Procurement Notes

Verify the specific suffix '13' corresponds to the required 13 ms reset delay time during procurement. Confirm the 4.0 V threshold voltage matches the target application's requirements. Ensure compatibility with the SOT-23-3 footprint and active low open-drain output configuration. Check RoHS compliance status if mandated by project specifications. Validate that the -40°C to +85°C operating temperature range suits the intended environment.

Supervisors Selection Notes

Select this component when a precise 4.0 V detection threshold is needed for low-voltage digital circuits. The 13 ms delay is suitable for systems requiring faster reset assertion compared to standard 240 ms variants. Consider the open-drain output for flexible interfacing with various logic levels. The low power consumption makes it ideal for battery-operated devices where standby current minimization is critical for extended operational life.

Supervisors Part Context

This part belongs to the APX803L series of micro power voltage detectors from Diodes Incorporated. The series is engineered for cost-effective and space-constrained designs. The 'L' variant typically denotes specific accuracy or power characteristics within the family. It serves as a fundamental supervisory element in portable electronics and industrial control panels requiring reliable power management.

Supervisors Replacement Considerations

APX803L40-30SA-7 offers a similar form factor but with a different reset delay time. TC54VN4002ECB713 is a direct substitute from Microchip Technology with identical pinout and functional parameters.
