Supervisors datasheet and documents for APX803-44SRG-7

APX803-44SRG-7

Supervisors Overview

The APX803-44SRG-7 is a microprocessor supervisory circuit manufactured by Diodes Incorporated. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.32 V for undervoltage detection, with an overvoltage threshold of 4.44 V. The device provides an active high, push-pull output signal and includes a reset delay time of 240 ms. It is housed in a SOT-23-3 surface-mount package and supports an operating temperature range from -40 °C to +125 °C.

Supervisors Feature Summary

Provides precise power supply monitoring with dedicated undervoltage and overvoltage detection thresholds.
Delivers a stable logic-level reset signal via an active high, push-pull output driver.
Ensures reliable system initialization through a defined reset delay period following power-up.

Supervisors Applications

Microprocessor (MPU) power voltage detection
Digital system power supervision
Battery-powered device power management

Supervisors Procurement Notes

Verify the specific suffix 'SRG' against the manufacturer's current datasheet to confirm pinout compatibility and electrical characteristics. Ensure the component meets the required industrial temperature range specifications for the target application environment before finalizing procurement.

Supervisors Selection Notes

Select this component when an active high reset signal is required for downstream logic circuits. The push-pull output capability allows direct interfacing with digital inputs without external pull-up resistors. Consider the 240 ms delay duration to ensure it aligns with the system's power-up timing requirements.

Supervisors Part Context

This part belongs to the APX803 series of low-power voltage detectors designed for microprocessor applications. It offers a compact three-pin SOT-23 footprint suitable for space-constrained designs. The series provides various threshold options to accommodate different standard voltage rails commonly used in embedded systems.
