Overview
The MAX40002ANS02+T is a single-channel analog comparator in a 4-bump WLP 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 a noninverting input. An internal reference voltage is preset at 0.2V, resulting in a switching threshold between 174mV and 226mV across the -40°C to +125°C temperature range. Propagation delay is typically 9µs with 100mV overdrive.
Feature Summary
- Ultra-low power consumption preserves battery life in portable applications
- Tiny footprint saves board space in compact designs
- Internal filtering provides high RF immunity
- High impedance maintained at inputs even when powered down
Applications
- Mobile Devices
- Portable Medical Devices
- Notebook Computers
- Electronic Toys
Procurement Notes
Verify the specific suffix '02' confirms the factory-trimmed 0.2V internal reference voltage. Ensure the 'ANS' designation matches the required 4-bump WLP package type for your layout. Confirm that the open-drain output configuration aligns with your system's pull-up requirements. Check the latest datasheet revision for any updates to absolute maximum ratings or thermal characteristics before finalizing procurement.
Selection Notes
Select this component when board space is constrained by the ultra-tiny 0.73mm x 0.73mm footprint. Choose it for applications requiring extremely low quiescent current to extend battery life. Use this part if a fixed 0.2V threshold is suitable for your signal detection needs. Consider the open-drain output requirement for interfacing with different logic voltage levels.
Part Context
This device belongs to the nanoPower MAX40002–MAX40005 family of tiny, single comparators designed for portable electronics. These devices are optimized for tight board space and power constraints found in modern mobile and handheld equipment. The family offers various reference voltages and output configurations to suit diverse application requirements.
Replacement Considerations
Other members of the MAX40002–MAX40005 family share identical pinouts and electrical characteristics but differ in internal reference voltage or output stage. Verify that alternative parts match the required 0.2V reference and open-drain output specifications.
