MAX9119EXK+T

Overview

The MAX9119EXK+T is a nanopower analog comparator in a 5-pin SC70 package. It operates on a single supply from +1.6V to +5.5V with a typical supply current of 350nA. The device features a CMOS push-pull output stage capable of sourcing and sinking up to ±5mA, providing rail-to-rail output swing. Input voltage range extends 200mV beyond the supply rails. It includes internal hysteresis for clean switching and prevents phase reversal for overdriven inputs.

Feature Summary

• Space-saving 5-pin SC70 package
• Ultra-low supply current consumption
• Beyond-the-Rails input voltage range
• CMOS push-pull output stage

Applications

• 2-Cell Battery Monitoring/Management
• Ultra-Low-Power Systems
• Mobile Communications
• Threshold Detectors/Discriminators
• Telemetry and Remote Systems

Procurement Notes

Verify the specific ordering suffix EXK+T against the manufacturer's official documentation to confirm the SC70-5 package and lead-free status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the component meets RoHS compliance requirements for your region before finalizing procurement.

Selection Notes

Select the MAX9119EXK+T when a push-pull output is required without an internal reference. Choose this part over the MAX9118 or MAX9120 if open-drain outputs are not needed. Verify that the 350nA supply current meets the system's power budget constraints compared to higher-power comparator alternatives.

Part Context

This component belongs to the MAX9117–MAX9120 family of nanopower comparators designed for low-voltage battery-powered applications. The MAX9119 variant specifically excludes the internal reference found in the MAX9117/MAX9118 models, resulting in lower quiescent current while maintaining the same compact footprint and electrical characteristics.
