What are the key features of MCP6566T-E/OT?
- 1.8V to 5.5V single-supply operation enabling direct use in low-voltage 1.8V and 3.3V logic systems
- Open-drain output supporting wired-OR configurations for shared interrupt lines with external pull-up flexibility
- 5 nA maximum input bias current in tiny 5-pin SOT-23 package for minimal loading on high-impedance signal sources
What is MCP6566T-E/OT used for?
The MCP6566T-E/OT is used in threshold detection circuits for battery voltage monitoring, over-temperature protection, and GPIO interrupt generation in microcontroller-based systems powered from 1.8V to 5.5V. Its open-drain output allows multiple comparators to share a single pull-up resistor on a wired-OR interrupt bus without level-translation logic. The 5-pin SOT-23 package is ideal for space-constrained portable and IoT designs where a dedicated comparator conserves MCU ADC resources.

Frequently Asked Questions
What supply voltage range does MCP6566T-E/OT support and how does this help in mixed-voltage system designs?
The MCP6566T-E/OT operates from 1.8V to 5.5V single supply, allowing it to interface directly with 1.8V MCUs on the input side and drive a 3.3V or 5V open-drain pull-up without level translation. This voltage flexibility is valuable in mixed-supply IoT boards where different subsystems operate at 1.8V and 3.3V simultaneously.
For a battery over-discharge protection circuit, how quickly can MCP6566T-E/OT respond to a threshold crossing?
The MCP6566T-E/OT provides a propagation delay of approximately 4 µs at 1.8V supply, fast enough for battery voltage monitoring circuits that need to flag an under-voltage event and trigger a load disconnect before the cell drops below its 2.5V minimum cutoff. The 5 nA input bias current ensures the voltage divider resistors can be in the megaohm range without offset error.
When would MCP6566T-E/OT be selected over an op-amp configured as a comparator in a 3.3V embedded design?
MCP6566T-E/OT is preferred over an op-amp when a rail-to-rail open-drain output with defined propagation delay is required, since general-purpose op-amps lack output stage optimization for digital logic levels. The dedicated comparator architecture ensures clean transitions on the open-drain output at 3.3V with a 10 kΩ pull-up, avoiding the linear region oscillation issues common with op-amp comparator circuits.
