Key Features
- 1.8 V minimum supply voltage enables direct operation from low-voltage battery and IoT system rails without a level-shift stage
- Push-pull output eliminates the need for an external pull-up resistor, simplifying PCB layout and reducing component count in space-constrained comparator circuits
- 0.005 µA maximum input bias current minimizes loading on high-impedance reference and sensor inputs, maintaining threshold accuracy in resistor divider and photodiode detection circuits
Applications
The MCP6561T-E/LT is suited for voltage threshold detection in battery-powered IoT devices, wearables, and portable instruments where the comparator must operate reliably from a 1.8 V supply rail. Its push-pull output directly drives CMOS logic inputs without external pull-up resistors, simplifying integration with low-voltage microcontrollers. It also suits overcurrent detection, window comparator circuits, and zero-crossing detection in motor control and power management applications.

Frequently Asked Questions
What minimum supply voltage does MCP6561T-E/LT support, and why does this matter for battery-powered IoT designs?
The MCP6561T-E/LT operates from a minimum supply voltage of 1.8 V, allowing it to function directly from a single lithium coin cell, two AA alkaline cells at end-of-discharge, or regulated 1.8 V rails common in IoT SoCs. This eliminates the need for a boost converter or level shifter to power the comparator, reducing BOM cost and quiescent current in battery-powered sensor nodes and wearable devices.
How does the push-pull output of MCP6561T-E/LT differ from open-drain comparators, and when should each be chosen?
The MCP6561T-E/LT's push-pull output actively drives both logic high and logic low, providing fast edge transitions without an external pull-up resistor. This reduces component count and speeds up output rise times, which is advantageous in single-supply CMOS logic interfaces. Open-drain outputs are preferred when wired-OR bussing of multiple comparator outputs is needed or when the output must swing to a different voltage rail than the comparator supply.
What input offset voltage does MCP6561T-E/LT specify, and how does it affect threshold accuracy in a voltage level detector?
The MCP6561T-E/LT has a maximum input offset voltage of 10 mV (10000 µV). For a battery voltage monitor comparing against a 2.5 V reference, this 10 mV offset creates a threshold uncertainty of ±10 mV around the trip point, equivalent to approximately 0.4% of the nominal threshold. For applications requiring tighter threshold accuracy, a precision comparator with sub-1 mV offset should be selected instead.
In what package does MCP6561T-E/LT come, and how does the T suffix affect purchasing for high-volume production?
The MCP6561T-E/LT is packaged in the SC-70 5-pin package, measuring approximately 2.0 mm x 2.1 mm — one of the smallest 5-pin surface-mount packages available, suitable for ultra-compact PCB layouts. The T suffix indicates tape-and-reel packaging, typically supplied in reels of 3000 units, which is the standard format for automated pick-and-place SMT assembly in high-volume consumer and IoT production runs.
