MAX40012ANS09+T

Overview

The MAX40012ANS09+T is a nanoPower single comparator in an ultra-tiny 4-bump WLP package with a 0.73mm x 0.73mm footprint. It operates on a supply voltage range of 1.7V to 5.5V and consumes only 500nA of supply current. The device features a noninverting input, open-drain output, and a factory-trimmed internal reference voltage of 0.9V (typical). It maintains high impedance at the inputs even when powered down and includes internal filtering for high RF immunity.

Feature Summary

• Ultra-low power consumption preserves battery life in constantly monitoring applications
• Tiny 4-bump WLP package saves board space in compact designs
• High input impedance maintained even when the device is powered down
• Internal filtering provides high RF immunity against noise

Applications

• Mobile Devices
• Portable Medical Devices
• Notebook Computers
• Electronic Toys

Procurement Notes

Verify the specific suffix '09' confirms the 0.9V internal reference voltage. Confirm the 'ANS' designation indicates the 4-bump WLP package type. Ensure the '+T' suffix matches the required tape-and-reel packaging format for your assembly process. Cross-reference the manufacturer's latest ordering guide for any potential future product status changes or availability updates.

Selection Notes

Select this component when board space is extremely limited due to its miniature 4-bump WLP form factor. Choose it for battery-operated systems requiring minimal quiescent current draw. Use this part if a fixed 0.9V threshold is suitable for your application, eliminating the need for external reference components. Verify that the open-drain output configuration aligns with your downstream logic requirements.

Part Context

This device belongs to the MAX40002–MAX40005 and MAX40012–MAX40015 family of nanoPower comparators. These parts are designed for portable electronics with tight space and power constraints. The family offers various input polarities, output types, and internal reference voltages across both WLP and SOT23 packages.

Replacement Considerations

Other members of the MAX40002–MAX40015 family may serve as alternatives if different input polarities, output structures, or reference voltages are needed while maintaining the same package and low-power characteristics.
