Overview
The MAX40002AUK02+ is a single-channel analog comparator from the nanoPower family, housed in a 5-pin SOT-23 package. It operates on a supply voltage range of 1.7V to 5.5V with a typical supply current of 500nA. The device features an open-drain output and non-inverting input configuration. An internal reference voltage is factory-trimmed to 200mV (typical). Key electrical parameters include a propagation delay of 9µs, an input offset voltage of 500µV, and an operating temperature range from -40°C to +125°C.
Feature Summary
- Ultra-low power consumption preserves battery life in portable applications
- Tiny 5-pin SOT-23 package minimizes board space requirements
- Internal filtering provides high RF immunity against noise
- High impedance inputs maintain functionality even when powered down
Applications
- Mobile devices
- Portable medical devices
- Notebook computers
- Electronic toys
Procurement Notes
Verify the specific suffix '02+' confirms the 200mV internal reference voltage setting. Confirm the 'AUK' designation corresponds to the 5-pin SOT-23 package variant rather than the WLP option. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical characteristics remain unchanged.
Selection Notes
Select this part when board space is constrained by the small SOT-23 footprint. Choose this model specifically for its non-inverting logic and open-drain output capability. The low quiescent current makes it suitable for always-on monitoring circuits. Verify that the 200mV internal threshold aligns with your signal detection requirements without needing external references.
Part Context
This component belongs to the MAX40002–MAX40005 series of nanoPower comparators designed for extreme size and power efficiency. The series offers both WLP and SOT-23 packaging options with various internal reference voltages. The MAX40002AUK02+ represents the specific combination of the SOT-23 package, non-inverting input, open-drain output, and the 0.2V reference setting within this family.
Replacement Considerations
The MAX40002AUK02+T is the tape-and-reel version of this component.
