MAX8554EEE

Overview

The MAX8554EEE is a single-supply voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single input voltage and provides an active-low, push-pull reset output. The device features a manual reset input and operates within a supply voltage range of up to 5.5 V. It includes a fixed reset delay time of 225 ms and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides precise voltage supervision with a dedicated manual reset input for system control
• Delivers an active-low, push-pull reset signal to ensure robust logic interfacing
• Operates on a single power supply with low quiescent current consumption

Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered equipment requiring voltage monitoring
• Portable electronic devices needing reliable power supervision

Procurement Notes

Verify the specific threshold voltage variant required for the application, as the MAX8554 series offers multiple options. Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure compliance with RoHS standards if applicable to the project requirements.

Selection Notes

Select this component when a single-channel voltage monitor with manual reset capability is needed. Consider the specific threshold voltage that matches the target supply rail. Evaluate the 225 ms reset delay against system startup timing requirements. Verify that the SOT-23-5 package fits the PCB layout constraints.

Part Context

This part belongs to the MAX6854/MAX8554 family of single-supply supervisors. These devices are designed for cost-sensitive applications requiring reliable power management. The Maxim Integrated brand indicates its origin within Analog Devices' portfolio of mixed-signal solutions.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6854 or MAX8554 series that match the exact threshold voltage. Verify electrical specifications such as reset delay and quiescent current before substitution.
