MAX918ESA+

Comparators Overview

The MAX918ESA+ is a nanopower analog comparator manufactured by Analog Devices Inc./Maxim Integrated, housed in an 8-SOIC package. It operates on a single supply voltage ranging from 1.8V to 5.5V and draws a typical supply current of 750nA. The device features an internal 1.245V reference with ±1.5% accuracy and includes 4mV of internal hysteresis. It provides an open-drain output capable of sinking up to 50mA and supports Beyond-the-Rails inputs extending 200mV beyond the supply rails.

Comparators Feature Summary

• Features an integrated 1.245V reference for simplified threshold detection
• Supports input voltages extending 200mV beyond the supply rails
• Includes internal hysteresis to ensure clean switching without external components
• Open-drain output stage suitable for mixed-voltage system designs

Comparators Applications

• 2-cell battery monitoring and management systems
• Ultra-low-power portable electronic devices
• Threshold detectors and discriminators
• Sensing applications at ground or supply lines

Comparators Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number matches the specific MAX918ESA+ designation and check for lead-free/RoHS compliance markings on the package. Ensure the supplier provides valid traceability documentation to guarantee the integrity of the semiconductor device.

Comparators Selection Notes

Select this component when an internal voltage reference is required to minimize external parts count. Choose the open-drain output configuration if wire-OR logic or level shifting between different voltage domains is necessary. This device is appropriate for designs prioritizing minimal static power consumption while maintaining reliable operation across varying temperature conditions.

Comparators Part Context

This part belongs to the MAX917–MAX920 family of nanopower comparators designed for space-saving SOT23 and SO packages. The family offers options with and without internal references, as well as push-pull and open-drain outputs. These comparators are engineered for low-voltage operation and high efficiency in battery-powered applications.

Comparators Replacement Considerations

The MAX917ESA+ serves as a functional substitute within the same family, offering identical specifications except for its push-pull output stage instead of open-drain.
