MAX9027EBT+TG47

Overview

The MAX9027EBT+TG47 is a nanopower analog comparator in a 6-bump UCSP package. It operates on a single supply voltage ranging from +1.8V to +5.5V with a typical supply current of 0.6µA at +5V. The device features Beyond-the-Rails inputs extending 200mV beyond the supply rails and utilizes a CMOS push-pull output stage capable of ±5mA drive. It includes internal hysteresis for clean switching and guarantees operation within a temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with 0.6µA supply current
• Beyond-the-Rails input voltage range extending 200mV past supply rails
• CMOS push-pull output stage with ±5mA drive capability
• Internal hysteresis prevents oscillation during slow signal transitions

Applications

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

Procurement Notes

Verify the specific suffix 'G47' against official manufacturer documentation, as standard listings typically utilize '+T' or '+T&R'. Confirm RoHS compliance status associated with the exact ordering code. Ensure the UCSP-6 footprint matches your PCB design guidelines. Validate that the component meets the required operating temperature range for your specific application environment before finalizing procurement.

Selection Notes

Select this component when ultra-low quiescent current is critical for battery life extension. The push-pull output eliminates the need for external pull-up resistors, simplifying circuit design compared to open-drain variants. The Beyond-the-Rails feature allows sensing near ground or supply lines without level shifting. Consider the MAX9028 if an open-drain output is preferred for mixed-voltage logic interfacing.

Part Context

This part belongs to the MAX9025–MAX9028 family of nanopower comparators manufactured by Analog Devices (Maxim Integrated). The family shares identical pinouts and core electrical characteristics, differing primarily in output configuration and the presence of an internal reference voltage. The MAX9027 specifically provides a push-pull output without an internal reference, distinguishing it from the MAX9025/26 which include a 1.236V reference.

Replacement Considerations

The MAX9028EBT+T is a direct functional substitute offering identical performance with an open-drain output instead of push-pull. Other family members like the MAX9025EBT+T provide similar low-power operation but include an internal reference voltage.
