Applications
The MCP6561T-E/OT is ideal for battery protection circuits, power supply voltage monitors, and over-temperature threshold detectors in portable devices requiring a single supply comparator with minimal PCB footprint. Its push-pull CMOS output directly drives microcontroller interrupt pins or LED indicators without external pull-up components, simplifying circuit design. The 1.8 V minimum supply enables operation from lithium coin cells and single AA batteries in low-power sensing applications.

Frequently Asked Questions
What makes the push-pull output of the MCP6561T-E/OT advantageous over open-drain comparators?
The MCP6561T-E/OT's push-pull CMOS output actively drives both high and low output states without an external pull-up resistor, resulting in faster output rise times and one fewer component per comparator instance in the BOM. For 3.3 V microcontroller interrupt inputs, the CMOS output swings rail-to-rail providing clean logic levels, whereas open-drain comparators require a separate 10 kΩ pull-up resistor and exhibit slower rising edges limited by the RC time constant.
For a lithium battery under-voltage lockout circuit, how does MCP6561T-E/OT operate near the cell cutoff voltage?
The MCP6561T-E/OT operates down to 1.8 V supply voltage, allowing it to remain active as a Li-ion cell discharges from 4.2 V to 3.0 V — well above its minimum supply. Connecting a resistive divider to set the comparator threshold at 3.0 V on the cell voltage allows the push-pull output to disable load switches at the 3.0 V cutoff, protecting the 5 nA bias current input from false triggering due to high-impedance divider source resistance.
Which SOT-23-5 package comparators are pin-compatible with MCP6561T-E/OT for second-source qualification?
The MCP6561T-E/OT in SOT-23-5 shares the standard pinout used by Texas Instruments TLV3201 and Maxim MAX9060 single comparators, all featuring VCC, GND, IN+, IN-, and output in the same 5-pin configuration with 0.95 mm pitch. Input bias currents range from 5 nA to 25 nA across alternatives, so second-source qualification should verify that the replacement meets the 5 nA maximum bias current specification for the target high-impedance circuit.
At 1.8 V supply, what propagation delay performance can be expected from the MCP6561T-E/OT in fast pulse detection?
At 1.8 V supply and 5 mV overdrive, the MCP6561T-E/OT typically exhibits propagation delay below 200 ns, enabling reliable detection of pulse edges at frequencies up to 1 MHz in threshold crossing applications. This speed is adequate for zero-crossing detection in audio signals up to 20 kHz, battery voltage monitoring with 100 µs response time requirements, and mechanical switch debouncing circuits with 500 µs hysteresis timing.
