Overview
The MAX40001AUT12+T is a single-channel analog comparator in a 6-pin SOT-23 package. It operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 0.9µA. The device features an open-drain output and includes a factory-trimmed internal voltage reference of 1.252V. Electrical specifications include a maximum input offset voltage of 14mV, propagation delay under 10µs, and operation across a temperature range of -40°C to +125°C.
Feature Summary
- Integrates a precision voltage reference to eliminate external components
- Provides ultra-low power consumption for extended battery life
- Features internal hysteresis to prevent output oscillation from noise
- Offers rail-to-rail input common-mode voltage range
Applications
- Cell phones and portable instruments
- Notebook computers and tablets
- Electronic toys and consumer accessories
- Portable medical instruments and wearables
- Battery level detectors
Procurement Notes
Verify the specific ordering suffix to confirm the package type and internal reference voltage value. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required operating temperature range and output configuration for the target application design.
Selection Notes
Select this component when board space is limited and low quiescent current is critical. The open-drain output requires an external pull-up resistor. Choose based on the specific internal reference voltage needed for the threshold detection circuit. Consider the push-pull MAX40000 if an active high output without external resistors is preferred.
Part Context
This part belongs to the MAX40000/MAX40001 family of nanoPower comparators designed for tight power and space constraints. The series provides options for different internal reference voltages and output stages. It serves as a compact solution for portable electronics requiring precise voltage monitoring with minimal power overhead.

FAQ
What is the function of the REF pin?
The REF pin outputs the internal voltage reference. It should be bypassed with a 0.1µF capacitor to ground close to the device.
How does the open-drain output work?
The open-drain output requires an external pull-up resistor connected to a voltage up to 5.5V to function correctly.
