MAX9027EBT+T

Overview

The MAX9027EBT+T is a nanopower analog comparator in a 6-bump UCSP package. It operates on a single supply from +1.8V to +5.5V with a typical supply current of 0.6µA at +5V. The device features a CMOS push-pull output stage capable of ±5mA drive and rail-to-rail swing. Input voltage range extends 200mV beyond the rails, and it includes internal hysteresis for clean switching.

Feature Summary

• Ultra-low power consumption without an internal reference
• Push-pull output stage with large drive capability
• Input common-mode range extends beyond supply rails
• Internal hysteresis prevents output oscillation

Applications

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

Procurement Notes

Verify the component matches the specific part number MAX9027EBT+T. Confirm the presence of the lead-free suffix (+) and tape-and-reel packaging (T). Ensure the manufacturer is Analog Devices Inc./Maxim Integrated. Check that the device is intended for commercial temperature ranges (-40°C to +85°C).

Selection Notes

Select this component when a push-pull output is required without the need for an internal voltage reference. It is suitable for designs needing rail-to-rail input operation below the negative supply rail. Consider the open-drain MAX9028 variant if mixed-voltage logic interfacing or wire-OR configurations are necessary.

Part Context

This device belongs to the MAX9025–MAX9028 family of nanopower comparators. Unlike the MAX9025/MAX9026, which include an internal 1.236V reference, the MAX9027/MAX9028 omit this feature to achieve lower supply currents. All variants share the same miniature 6-bump UCSP package footprint.

Replacement Considerations

The MAX9028EBT+T serves as a direct functional substitute if an open-drain output is acceptable instead of push-pull.
