Overview
The MAX40014ANS09+T is a single-channel analog comparator in a 4-bump WLP package. It features a noninverting input and push-pull output. The supply voltage range is 1.7V to 5.5V with a typical operating current of 500nA. Input voltage ranges from 0.1V to VCC + 0.1V. Internal reference voltage is preset at 0.9V (882mV min, 918mV typ). Propagation delay is typically 9µs for high-to-low transitions. Operating temperature spans -40°C to +125°C.
Feature Summary
- Ultra-tiny 4-bump wafer-level package saves board space
- Push-pull output stage eliminates need for external pullup resistor
- Internal factory-trimmed reference voltage simplifies design
- High impedance inputs maintained even when powered down
Applications
- Mobile devices
- Portable medical devices
- Notebook computers
- Electronic toys
Procurement Notes
Verify the specific suffix '09' corresponds to the required 0.9V internal reference threshold. Confirm the 'ANS' designation matches the 4-bump WLP package requirement rather than the SOT23 option. Ensure the noninverting input polarity aligns with the circuit logic requirements before finalizing procurement.
Selection Notes
Select this part when a compact footprint is critical and an active-high output state is needed upon exceeding the threshold. The push-pull architecture allows direct interfacing with digital logic without external components. Verify that the 0.9V switching point meets the application's signal detection needs compared to other available reference options.
Part Context
This component belongs to the nanoPower family of comparators designed for extreme power efficiency and minimal size. It shares architectural similarities with the MAX40002–MAX40005 series but offers distinct input polarities and output configurations. The device targets battery-operated portable electronics where board real estate and quiescent current are primary constraints.
Replacement Considerations
MAX40014AUK09+T provides the same electrical characteristics in a 5-pin SOT23 package instead of the WLP form factor.
