APX803L05-30SA-7

Supervisors Overview

The APX803L05-30SA-7 is a supervisor IC from Diodes Incorporated featuring a fixed 2.93V reset threshold voltage and a 300ms reset pulse width. It operates within a supply voltage range of 1.6V to 5.5V, ensuring reliable monitoring for low-voltage systems. The device provides an active-low push-pull output and includes a manual reset input pin for external control. Packaged in a compact SOT-23-5 format, it integrates essential power management functions with high accuracy and low quiescent current consumption.

Supervisors Feature Summary

• Fixed reset threshold voltage ensures precise monitoring of supply rails without external resistor networks.
• Active-low push-pull output driver supports direct interfacing with microcontroller reset pins.
• Manual reset input allows system initialization or forced reset states via external logic signals.

Supervisors Applications

• Microcontroller and DSP power supply supervision
• Battery-operated portable devices requiring low standby current
• Embedded systems with strict reset timing requirements

Supervisors Procurement Notes

Verify the exact part number against manufacturer datasheets to confirm the specific threshold voltage and package variant. Ensure compatibility with your system's operating voltage range and reset polarity requirements before procurement. Cross-reference ordering codes with official distributor catalogs to avoid substitution errors.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for accurate power monitoring. Consider the 300ms delay for noise immunity and the manual reset feature for system control flexibility. Evaluate the SOT-23-5 package size constraints and ensure the active-low output matches your target controller's input specifications.

Supervisors Part Context

This part belongs to the APX803 series of voltage supervisors designed for low-power applications. It complements other variants in the family that offer different threshold voltages and reset delays, allowing designers to tailor power management solutions to specific voltage rails and timing needs across various embedded platforms.

Supervisors Replacement Considerations

Check for equivalent parts with matching 2.93V thresholds and 300ms delays. Verify pinout compatibility for SOT-23-5 packages. Confirm active-low output polarity and manual reset functionality in potential substitutes to ensure seamless integration without circuit redesign.
