MAX9100EUK+T 概要
A micropower comparator is a voltage-regulator-family analog semiconductor that compares two input voltages and produces a push-pull logic output indicating their relationship. The MAX9100 belongs to the comparator hierarchy and is used as a simple decision element, protection element, or threshold detector between an analog sensor and a digital system. Its low supply voltage and low quiescent current make it suitable for single-cell and coin-cell powered equipment.
Key features include operation from a single 1.0V to 5.5V supply, 5µA quiescent current, rail-to-rail input capability, and an open-drain output according to the manufacturer comparison information. The common-mode input range includes the negative supply rail, which helps monitor low-voltage battery signals. The MAX9100EUK+T is specified in the 5-pin SOT-23 package and is supplied in tape-and-reel packaging.
The MAX9100 is intended for low-energy signal-chain designs where the comparator must operate directly from a depleted battery or regulated low-voltage rail. Because its supply range begins at 1.0V, it can remain useful as the battery approaches its discharge endpoint. The device is optimized for single-cell systems rather than high-voltage industrial comparison tasks.
Typical applications include battery threshold detection, portable sensor interfaces, low-voltage power sequencing, window or level comparison, and simple over-discharge indication. In these systems, the comparator can establish whether a measured voltage is above or below a reference without requiring a powered analog front end with a higher minimum supply.
Designers should verify the exact output topology, input limits, propagation delay, and operating-temperature ratings against the current manufacturer datasheet before layout. Input and supply decoupling should be placed close to the device, and unused comparator inputs must not be left floating. The manufacturer application information is the authoritative reference for electrical limits and recommended usage.
This product page combines verified manufacturer and distributor information with practical application guidance, pricing context, and design considerations that help engineers evaluate the MAX9100EUK+T for low-voltage battery systems.

主な用途
MAX9100EUK+T の用途: 6 件s: Single-Cell Battery Threshold Monitoring, Portable Sensor Threshold Detection, Low-Voltage Power Sequencing, Battery-Powered Level Comparison, Over-Discharge Indication, Portable Analog-to-Digital System Interface.
Single-Cell Battery Threshold Monitoring
The MAX9100EUK+T fits single-cell battery threshold monitoring because it operates from a 1.0V to 5.5V supply and has a quoted 5µA quiescent current. Place the battery voltage or a resistor-divided battery signal on one input and a reference on the other input to create an early-warning or low-battery decision. Its input common-mode range includes the negative rail, which supports low-level monitoring. Because the output is described as open-drain in the provided comparison data, use the required pull-up arrangement and verify timing against the MAX9100/MAX9101 datasheet.
おすすめ
Portable Sensor Threshold Detection
The MAX9100EUK+T is suitable for portable sensor threshold detection when a sensor output must be converted into a simple digital alert. Its 1.0V minimum supply supports low-voltage sensor rails, while the 5µA quoted quiescent current helps preserve battery energy. The comparator can compare a sensor signal with a reference or divided output and provide a rail-to-rail-related decision function. Designers should check input offset, noise, propagation delay, and the external pull-up required by the open-drain output before setting the threshold.
おすすめ
Low-Voltage Power Sequencing
The MAX9100EUK+T can be used in low-voltage power-sequencing circuits that decide whether a monitored rail has crossed an operating threshold. Its single-supply operation from 1.0V to 5.5V matches small battery-backed systems, and the 5µA quoted quiescent current limits standby demand. Place the sequencing decision around a precision reference and carefully evaluate startup transients, propagation delay, and pull-up behavior. The manufacturer datasheet should control the final logic threshold and timing budget.
おすすめ
Battery-Powered Level Comparison
The MAX9100EUK+T is appropriate for level comparison in compact battery-powered products because it combines low supply voltage with low quiescent current. It can compare a divided analog level against a reference to detect tank, meter, or sensor thresholds. The wide input common-mode range, including the negative rail, provides flexibility when the measured signal is close to ground. Use short traces, stable reference components, and the open-drain pull-up specified by the manufacturer to avoid introducing noise or excessive delay.
おすすめ
Over-Discharge Indication
The MAX9100EUK+T can implement over-discharge indication in a low-energy system by comparing a divided battery voltage with a reference threshold. Its ability to operate down to a 1.0V single supply is useful as the cell voltage declines, while the 5µA quoted quiescent current reduces the impact of continuous monitoring. The circuit should include an appropriate pull-up for the open-drain output and account for reference tolerance and comparator offset. Verify the exact electrical limits in the MAX9100/MAX9101 datasheet before production release.
おすすめ
Portable Analog-to-Digital System Interface
The MAX9100EUK+T can serve as a simple threshold element ahead of a portable ADC or digital controller. It compares an analog condition with a reference and provides a binary result without requiring the higher supply voltage of many conventional comparators. This is useful in portable instrumentation where the comparator itself must operate from a low-energy rail. Design the reference for stability, keep the comparator input path short, and review propagation delay and output loading so that the decision remains reliable across temperature and supply variation.

設計ノート
The MAX9100EUK+T is specified for a 1.0V to 5.5V single supply, so check the battery's loaded voltage and the regulator's dropout behavior before finalizing the power budget. Place the supply bypass capacitor close to the device and keep the comparator's continuous operating current in the system-level battery-life calculation. The 5µA quiescent figure should be used together with output-state, pull-up, input, and leakage currents.
Route comparator inputs and the reference signal away from switching nodes and high-current return paths. Use a compact ground reference, short input traces, and local supply decoupling to reduce noise pickup. Because the product is provided in a 5-pin SOT-23 package, verify the exact land pattern and pin numbering from the manufacturer datasheet before releasing the PCB artwork.
Do not treat a functional-equivalent comparator as an automatic replacement. The package, pin functions, input common-mode limits, output topology, propagation delay, and supply range must all be checked. In particular, the provided material associates MAX9100EUK+T with an open-drain output, so the pull-up network and downstream logic must be designed around that behavior rather than an assumed push-pull output.
