Overview
The MAX40001ANT12+T is a single-channel comparator with an integrated voltage reference, housed in a 6-bump WLP package. It operates on a supply voltage of 1.7V to 5.5V and consumes 0.9µA typical supply current. The device features an open-drain output, 1.252V internal reference, and -0.2V to VDD + 0.2V input common-mode range. Propagation delay is typically 14µs at 100mV overdrive. Input offset voltage is 8mV maximum, with 2.5mV internal hysteresis. Operating temperature spans -40°C to +125°C.
Feature Summary
- Built-in precision voltage reference eliminates external components
- Open-drain output allows flexible logic level translation
- Internal filtering provides high RF immunity
- Rail-to-rail input range extends beyond supply rails
Applications
- Cell phones
- Portable instruments
- Notebook computers
- Level detectors
- Battery-powered systems
Procurement Notes
Verify the specific ordering suffix matches the required package type and reference voltage. Confirm RoHS compliance status for environmental regulations. Check production availability as some variants may be marked as future products or discontinued. Ensure the open-drain configuration aligns with system pull-up requirements.
Selection Notes
Select this component when board space is limited due to its ultra-compact WLP footprint. Choose the open-drain variant if multiple comparators need to share a single pull-up resistor or require logic level shifting. Verify that the 1.252V internal reference meets the threshold accuracy needs without requiring external trimming.
Part Context
Part of the nanoPower family designed for extreme power efficiency. Shares the same core architecture and pinout as the MAX40000, differing primarily in the output stage structure. Designed specifically for portable electronics where tight power and space constraints are critical design factors.
Replacement Considerations
MAX40000ANT12+T offers identical electrical characteristics except for the push-pull output stage instead of open-drain.
FAQ
How does the open-drain output affect logic level translation?
The open-drain output can be pulled up to any voltage up to 5.5V, allowing it to interface with different logic levels than the VDD supply voltage.
What is the function of the REF pin?
The REF pin outputs the internal 1.252V reference voltage and should be bypassed with a capacitor close to the device for stability.
