Overview
The MAX40000ANT12+T is a single, ultra-low-power comparator featuring an integrated 1.252V voltage reference. It operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 0.9µA. The device utilizes a 6-bump wafer-level package (WLP) measuring 1.11mm x 0.76mm. Key electrical characteristics include an input common-mode voltage range from -0.2V to VDD + 0.2V, propagation delay under 10µs, and internal hysteresis of 2.5mV. It supports the automotive temperature range of -40°C to +125°C.
Feature Summary
- Integrates a factory-trimmed precision voltage reference to eliminate external components.
- Features micropower operation to preserve battery life in portable electronics.
- Provides high RF immunity through internal filtering mechanisms.
- Offers rail-to-rail output swing with minimal supply current surges during switching.
Applications
- Cell phones
- Portable medical instruments and wearables
- Level detectors
Procurement Notes
Verify the specific ordering suffix to confirm the package type and reference voltage. Ensure the selected variant matches the required output configuration and thermal specifications for the target application environment.
Selection Notes
Select this component for designs requiring minimal board space and ultra-low quiescent current. The built-in reference simplifies circuit design by removing the need for external voltage sources. Consider the WLP footprint constraints when planning the PCB layout.
Part Context
This part belongs to the MAX40000/MAX40001 family of nanoPower comparators. These devices are designed for applications with tight power and space constraints. The family includes variants with different reference voltages and output stages to suit various system requirements.
Replacement Considerations
Direct replacements within the same family include MAX40000AUT12+T (SOT23 package) or other reference voltage variants like MAX40000ANT16+T. Verify pin compatibility and reference voltage accuracy before substitution.
FAQ
What is the function of the REF pin?
The REF pin outputs the internal 1.252V voltage reference. It should be bypassed with a 0.1µF capacitor to GND as close to the device as possible.
How does the MAX40001 differ from the MAX40000?
The MAX40001 features an open-drain output, whereas the MAX40000 has a push-pull output. Both share the same internal reference and power characteristics.
