Key Features
- Dual comparator with 1.6 V minimum supply voltage and open-drain outputs for wired-OR and level-shifting applications
- Ultra-low 0.0001 µA input bias current enables accurate threshold detection with high-impedance signal sources
- Compact MSOP-8 package integrates 2 comparator channels in under 5 mm x 3 mm PCB footprint
Applications
The MCP6547-I/MS is used in battery-powered threshold detection circuits, window comparators, and interrupt generation for microcontroller GPIO pins operating at 1.6 V to 5.5 V supply rails. Its open-drain architecture allows multiple comparator outputs to be wire-ORed together on a single line for fault detection in power management systems. The device also suits level-translation interfaces and over-current detection in portable consumer electronics and IoT edge devices.

Frequently Asked Questions
What is the minimum supply voltage for the MCP6547-I/MS and how does that benefit battery-powered designs?
The MCP6547-I/MS operates from as low as 1.6 V, enabling use in single alkaline or NiMH cell systems, and continues functioning as the battery discharges toward end-of-life voltage without adding a boost regulator, saving cost and PCB space.
Why are open-drain comparator outputs important in multi-comparator fault detection systems?
Open-drain outputs allow multiple MCP6547 channels or additional comparators to share a single pull-up resistor on a common fault line using wired-OR logic. Any channel pulling the line low immediately signals a fault condition to the host microcontroller, simplifying the interrupt routing hardware.
How does the 7000 µV maximum input offset voltage of the MCP6547-I/MS affect threshold accuracy in low-level signal detection?
A 7000 µV offset means that the actual trip point can deviate up to 7 mV from the intended reference voltage. Designers targeting precision detection thresholds tighter than 10 mV should add hysteresis or use a lower-offset comparator, while general-purpose threshold detection at signals above 100 mV is largely unaffected.
