What are the key features of MAX9100EUK+T?
- Ultra-low supply current of 5 µA typical, enabling battery-powered and energy-harvesting designs
- Operates from a single supply as low as 1.0 V, compatible with 1.2 V and 1.5 V battery systems
- Open-drain output allows wired-OR configurations and direct interfacing to multiple logic voltage levels
- Tiny SOT-23 5-pin package minimizes board area in space-constrained portable applications
What is MAX9100EUK+T used for?
The MAX9100EUK+T excels in battery-powered portable equipment such as wearables and medical sensors, where its 5 µA typical supply current extends battery life significantly. It is well-suited for threshold detection circuits, power-good monitors, and window comparator networks operating from single-cell Li-ion or coin-cell batteries. Its open-drain output and 1.0 V minimum supply also make it ideal for level-shifting and interfacing between 1.8 V and 3.3 V logic domains in IoT edge nodes.

Frequently Asked Questions
What is the minimum supply voltage that MAX9100EUK+T can operate from?
The MAX9100EUK+T operates from a single supply as low as 1.0 V, making it compatible with single-cell alkaline, coin-cell, and low-voltage lithium batteries. This allows use in ultra-low-power portable and wearable designs without a voltage regulator step-up stage, simplifying the overall power architecture.
How much supply current does MAX9100EUK+T draw, and why does that matter for battery life?
The MAX9100EUK+T draws only 5 µA typical supply current. In a coin-cell battery application with a 220 mAh capacity, this translates to over 44,000 hours of continuous operation from the comparator alone, making it an excellent choice for always-on threshold detection in IoT sensors and medical monitoring devices.
Which output topology does MAX9100EUK+T use, and how does it affect system design?
The MAX9100EUK+T uses an open-drain output topology, requiring an external pull-up resistor to the desired logic rail. This allows the output to pull up to voltages different from the comparator's supply—enabling wired-OR bus sharing and direct interfacing to 1.8 V, 3.3 V, or 5 V logic systems from a single 1.0 V comparator supply.
What package does MAX9100EUK+T come in and how does it benefit PCB layout?
The MAX9100EUK+T is housed in a 5-pin SOT-23 package with a footprint of approximately 1.6 mm × 2.9 mm, one of the smallest surface-mount packages available for comparators. This compact size reduces board area and is especially valuable in wearables, hearing aids, and densely populated portable PCBs where every square millimeter counts.
What is the input offset voltage specification for MAX9100EUK+T?
The MAX9100EUK+T has a maximum input offset voltage of 20,000 µV (20 mV). While this is relatively relaxed compared to precision comparators, it is well-suited for coarse threshold detection such as low-battery detection, switch debouncing, and simple window comparators where millivolt-level accuracy is not required.
