MAX9027EBT+TG05

Overview

The MAX9027EBT+TG05 is a single-channel nanopower comparator in a 6-bump UCSP package. It operates on a supply voltage range of +1.8V to +6V with a typical supply current of 0.6µA at +5V. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails and a CMOS push-pull output capable of ±5mA drive. Key electrical parameters include a maximum input offset voltage of 10mV over temperature, an input bias current of 2nA max, and propagation delays ranging from 6µs to 40µs depending on supply voltage.

Feature Summary

• Ultra-low power consumption requiring only 0.6µA supply current
• Input common-mode voltage extends 200mV beyond the supply rails
• Push-pull output stage provides rail-to-rail swing with ±5mA drive capability
• Internal hysteresis ensures clean switching without external components

Applications

• Two-cell battery monitoring and management systems
• Zero-crossing detection circuits
• Logic-level translation between different voltage domains
• Ultra-low-power mobile communications devices

Procurement Notes

Verify the specific suffix 'TG05' against official Maxim Integrated documentation to confirm tape-and-reel packaging details and lot traceability. Ensure the component matches the lead-free/RoHS-compliant status indicated by the '+' symbol. Cross-reference the manufacturer's ordering guide for exact availability and valid part number formatting before finalizing procurement orders.

Selection Notes

Select this component when a single comparator with push-pull output is required in a space-constrained design. It is suitable for applications needing operation down to +1.8V and input signals exceeding the supply rails. Choose this part over open-drain versions if direct sourcing and sinking of load current is necessary without external pull-up resistors.

Part Context

This device belongs to the MAX9025–MAX9028 family of nanopower comparators manufactured by Maxim Integrated (now Analog Devices Inc.). The family shares identical pinouts and core performance characteristics, differentiated primarily by output type and the presence of an internal reference voltage. The MAX9027 specifically offers a push-pull output without an internal reference.

Replacement Considerations

The MAX9025, MAX9026, and MAX9028 are pin-for-pin compatible replacements within the same family. Verify that the alternative part's output configuration (push-pull vs. open-drain) meets the circuit requirements.
