APX803L-23SA-7

Supervisors Overview

The APX803L-23SA-7 is a micropower voltage detector manufactured by Diodes Incorporated, designed for microprocessor supervisory circuits. It operates within a supply voltage range of 1.0 V to 5.5 V and features a fixed threshold voltage of 2.3 V. The device provides an active low, open-drain reset output with a typical reset delay time of 220 ms. It is housed in a compact SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Micropower consumption with typical supply current of 1 µA
• Fixed internal detection voltage levels without external components
• Active low open-drain reset signal output
• Compact three-pin SOT-23 surface-mount packaging

Supervisors Applications

• Microprocessor (µP) supervisory circuits
• Battery-powered portable devices
• Smartphone power management systems
• Internet equipment power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'SA' against the official Diodes Incorporated datasheet to confirm pinout configuration and tape-and-reel specifications. Ensure the selected variant matches the required thermal performance and package dimensions for the target PCB layout. Cross-reference the part number with authorized distributors to confirm current availability status and RoHS compliance documentation prior to procurement.

Supervisors Selection Notes

Select this component when a fixed 2.3 V threshold is required for system supervision. Consider the 1 µA quiescent current for battery efficiency. Verify that the open-drain output interface is compatible with the downstream logic inputs. Confirm that the SOT-23-3 package fits the available board space constraints.

Supervisors Part Context

This part belongs to the APX803L series of micropower voltage detectors developed by Diodes Incorporated. The series targets applications requiring minimal power burden during detection functions. Other variants in the family offer different fixed threshold voltages ranging from 1.2 V to 5.0 V in 0.1 V steps, sharing the same low-power architecture and package options.
