Overview
The MAX9017BEKA+T is a dual precision nanoPower comparator in an 8-pin SOT-23 package. It operates on a single supply from 1.8V to 5.5V with a typical supply current of 1.2µA at 1.8V and 1.4µA at 5.0V. The device features B-grade internal reference voltage of 1.24V ±1.75% (1.218V to 1.262V at +25°C). Input offset voltage is guaranteed up to 5mV max at +25°C and 10mV max over the -40°C to +85°C range. It includes built-in 4mV hysteresis, push-pull outputs capable of ±6mA drive, and Beyond-the-Rails inputs extending 200mV beyond the supply rails.
Feature Summary
- Dual precision comparators featuring integrated B-grade 1.24V reference
- Ultra-low power consumption suitable for battery-operated systems
- Beyond-the-Rails input capability extending 200mV past supply rails
- Push-pull output stage with high drive capability and crowbar-current-free switching
Applications
- Two-cell battery monitoring and management
- Threshold detectors and discriminators
- Window detectors
- Sensing at ground or supply line
- Telemetry and remote systems
Procurement Notes
Verify the specific suffix 'EKA/V+' against official documentation to confirm package type and RoHS status. Confirm AEC-Q100 Grade 3 qualification requirements if automotive applications are intended. Ensure operating conditions remain within the specified 1.8V to 5.5V supply range and -40°C to +85°C temperature limits.
Selection Notes
Select this component when low quiescent current and integrated reference are required in a compact SOT-23 form factor. The B-grade reference offers wider tolerance than the A-grade variant but eliminates the need for external components. Choose the push-pull output version for direct logic interfacing without pull-up resistors.
Part Context
Part of the MAX9015–MAX9020 family of nanoPower comparators designed for space-constrained, low-voltage applications. The dual configuration provides two independent comparison channels within a single 8-pin package, optimizing board area compared to single-channel alternatives.
Replacement Considerations
Direct replacements include other members of the MAX9015–MAX9020 series such as MAX9017AEKA+T or MAX9018BEKA+T, provided pinout and electrical characteristics match the design requirements.
