Overview
The MAX9120EXK+T is a nanopower analog comparator in a 5-pin SC70 package. It operates on a supply voltage range of +1.6V to +5.5V with a typical supply current of 350nA. The device features an open-drain output stage and Beyond-the-Rails inputs that extend 200mV beyond the supply rails. It includes internal hysteresis for clean switching and guarantees operation from -40°C to +85°C.
Feature Summary
- Ultra-low power consumption with 350nA supply current
- Beyond-the-Rails input capability extending 200mV past supply rails
- Open-drain output suitable for mixed-voltage logic translation
- Internal hysteresis prevents oscillation during slow signal transitions
Applications
- 2-Cell Battery Monitoring/Management
- Threshold Detectors/Discriminators
- Telemetry and Remote Systems
- Medical Instruments
Procurement Notes
Verify the specific suffix 'EXK+T' corresponds to the SC70-5 package and tape-and-reel delivery format. Confirm RoHS compliance status via the manufacturer's official documentation, as indicated by the '+' designation. Ensure the component matches the Analog Devices / Maxim Integrated branding for authenticity.
Selection Notes
Select this part when low quiescent current is critical for battery life. Choose the open-drain configuration if interfacing with different voltage domains or implementing wire-OR logic. Verify that the propagation delay meets system timing requirements, as nanopower comparators typically exhibit slower response times than high-speed alternatives.
Part Context
This component belongs to the MAX9117–MAX9120 family of nanopower comparators. Unlike the MAX9117/MAX9118 variants, it lacks an internal reference voltage. It shares the same space-saving SC70 footprint and electrical characteristics regarding input range and supply current limits as its peers in the series.
Replacement Considerations
Check for MAX9120ESA+ if an 8-pin SO package is required instead of SC70. Other family members like MAX9119EXK+T offer push-pull outputs but share similar electrical profiles.
