Key Features
- Open-drain output compatible with multiple logic levels, enabling wired-OR configurations and flexible level shifting
- Ultra-low 0.005 µA maximum input bias current for accurate threshold detection with high-impedance signal sources
- 1.8 V minimum supply voltage in a 5-pin SOT-23 package, ideal for space-constrained low-voltage portable designs
Applications
The MCP6566UT-E/OT suits low-voltage threshold detection and signal comparison in portable medical devices, IoT sensor nodes, and wearable electronics operating from 1.8 V to 5.5 V supply rails. Its open-drain output supports wired-OR interrupt buses common in microcontroller systems where multiple comparators share a single interrupt line. The extended temperature rating and tiny SOT-23-5 package make it reliable for industrial sensor interfaces and compact battery-monitoring circuits.

Frequently Asked Questions
What supply voltage range does the MCP6566UT-E/OT support and what output type does it provide?
The MCP6566UT-E/OT operates from a 1.8 V to 5.5 V supply and features an open-drain output. The open-drain configuration allows the output to be pulled up to any logic voltage within the supply range, enabling easy interfacing with 3.3 V or 5 V microcontrollers even when the comparator itself runs at 1.8 V.
How does the MCP6566UT-E/OT perform in a battery-level detection circuit for a single-cell Li-ion system?
With a 0.005 µA maximum input bias current and 1.8 V minimum supply, the MCP6566UT-E/OT accurately monitors a resistor-divider threshold for a single-cell 3.7 V Li-ion battery down to near-cutoff voltage. The open-drain output pulls low to signal an interrupt to an MCU when battery voltage drops below the set threshold, with negligible quiescent current impact on overall system power budget.
Why is the 5-pin SOT-23 package of MCP6566UT-E/OT advantageous for wearable sensor designs?
The SOT-23-5 package measures approximately 2.9 mm x 1.6 mm, occupying minimal PCB area on wearable or implantable device boards where every square millimeter counts. Combined with the 1.8 V supply operation, this tiny footprint allows battery-powered comparator circuits to be placed near sensors in body-worn monitors, hearing aids, and compact IoT edge nodes without consuming significant board space.
When is the MCP6566UT-E/OT a better fit than a push-pull output comparator in a multi-node interrupt design?
The open-drain output of MCP6566UT-E/OT allows multiple comparator outputs to be wire-OR'd together on a shared interrupt line, which is not possible with push-pull outputs. In systems with 4 or more threshold detectors sharing a single MCU interrupt pin, the MCP6566UT-E/OT avoids bus contention while its 0.005 µA bias current minimizes the impact on the high-impedance shared pull-up node.
