What are the key features of MAX40009ANT+?
- Micropower supply current under 1 µA enables always-on threshold detection in coin-cell and energy-harvesting powered devices
- Push-pull output drives logic lines directly without external pull-up resistors, simplifying circuit design
- Ultra-compact 6-ball WLP (WLCSP) package fits in sub-1 mm grid arrays for space-critical wearable and IoT PCBs
What is MAX40009ANT+ used for?
The MAX40009ANT+ is ideal for battery life-sensitive IoT sensors, wearables, and medical patches that require continuous voltage level monitoring with minimal quiescent current drain. Its micropower architecture allows it to remain active during deep-sleep system states, waking the host processor only when a threshold event occurs. The 6-ball WLCSP package also benefits ultra-compact hearing aids, smart tags, and implantable device prototypes where every square millimeter of board space is critical.

Frequently Asked Questions
How low is the quiescent current of the MAX40009ANT+, and why does this matter for coin-cell designs?
The MAX40009ANT+ draws a maximum of 0.14 µA input bias current and operates with sub-1 µA supply current, allowing a 230 mAh CR2032 coin cell to power the comparator for several years in always-on threshold monitoring mode. This makes it practical for door sensors, asset trackers, and medical patches where battery replacement is inconvenient or impossible.
How does the push-pull output of the MAX40009ANT+ differ from open-collector comparator outputs in circuit design?
Unlike open-collector outputs that require an external pull-up resistor to define the logic-high level, the push-pull output of MAX40009ANT+ actively drives both high and low states, eliminating one passive component per comparator. This also results in faster rising edges when driving capacitive loads such as MOSFET gates, improving response times from several microseconds to under 100 ns.
What board area does the 6-ball WLP package of MAX40009ANT+ require compared to a standard SOT-23 comparator?
The 6-ball WLCSP package of MAX40009ANT+ occupies approximately 0.7 mm x 0.7 mm footprint, roughly 10 times smaller than a standard SOT-23-5 package at about 2.9 mm x 1.6 mm. This space reduction is significant in wearable devices, hearing aids, and implantable prototypes where PCB real estate directly impacts product dimensions and user comfort.
In which wearable sensing applications does the MAX40009ANT+ provide a practical advantage over larger comparators?
For wearable biosensors monitoring skin temperature or SpO2 thresholds, the MAX40009ANT+ provides always-on comparator function consuming under 1 µA, meaning a 10 mAh thin-film battery can sustain threshold detection for over 400 days without recharge. Its 5000 µV maximum input offset is acceptable for most sensor threshold applications where signal swings exceed 50 mV.
