APX803-29SRG-7

Supervisors Overview

The APX803-29SRG-7 is a micro-power voltage detector manufactured by Diodes Incorporated, designed for monitoring power supplies in microprocessor and digital systems. It features a fixed threshold voltage of 2.93 V with an active low open-drain output. The device operates within a supply voltage range of 1.1 V to 5.5 V and includes a reset delay time of 200 ms. It is housed in a SOT-23R-3 surface-mount package and supports an operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides precise voltage supervision for microprocessor systems with a fixed detection level.
• Features low supply current consumption to minimize impact on system power efficiency.
• Delivers an active low open-drain reset signal upon power failure or brown-out conditions.

Supervisors Applications

• Microprocessor supervisory circuits
• Battery-powered devices
• Smart phones
• Internet equipment

Supervisors Procurement Notes

Verify the specific suffix 'SRG' indicates the SOT-23R-3 package variant when sourcing replacements. Confirm that the threshold voltage matches the required 2.93 V specification for the target application. Ensure compatibility with the active low open-drain output configuration. Check for any design-in restrictions as the component may be subject to lifecycle changes.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for power supply monitoring. The SOT-23R-3 package is suitable for space-constrained surface-mount designs. Consider the 200 ms reset delay for timing requirements. Verify that the 1.1 V minimum operating voltage aligns with the system's lowest expected supply rail.

Supervisors Part Context

This part belongs to the APX803 series of micropower voltage detectors developed by Diodes Incorporated. The series targets applications requiring low burden on power efficiency, such as portable electronics. The APX803-29SRG-7 specifically denotes the 2.93 V threshold variant in the SOT-23R-3 package.

Supervisors Replacement Considerations

APX803-29SAG-7 offers the same electrical specifications but uses a standard SOT-23-3 package instead of the SOT-23R-3 variant. Verify pinout compatibility and physical footprint differences before substitution.
