Frequently Asked Questions
What output configuration does MCP6547-I/P use and how does it enable 3.3 V to 5 V logic level translation?
The MCP6547-I/P has open-drain outputs, which means a pull-up resistor tied to any target voltage rail sets the logic high level. By pulling the output to a 5 V rail while the comparator itself runs from 3.3 V, designers achieve simple 3.3 V-to-5 V translation with only a single passive resistor per channel.
How accurate are the switching thresholds of MCP6547-I/P when used for battery low-voltage detection at 1.8 V?
The MCP6547-I/P specifies a maximum input offset voltage of 7 mV, which directly adds threshold error to the resistor-divider reference. At a 1.8 V detection point, a 7 mV offset represents less than 0.4% error, providing accurate enough switching for most battery low-voltage cutoff and power-good comparator designs.
Can both MCP6547-I/P comparator channels be used independently in a window detector circuit?
Yes. The MCP6547-I/P contains 2 fully independent comparator channels in one 8-pin PDIP package, each with its own input pair and open-drain output. Connecting each channel to separate reference voltages lets designers build a window comparator that signals when an analog input exceeds either an upper or lower threshold.
What is the procurement lead time for MCP6547-I/P and is there a surface-mount alternative for production designs?
The MCP6547-I/P in PDIP-8 carries a factory lead time of approximately 11 weeks. For production PCBs requiring smaller footprints, Microchip offers the MCP6547T-I/SN in SOIC-8 with a 4.9 mm × 3.9 mm body, and the MCP6547T-I/ST in TSSOP-8 for higher-density SMT assembly.
