Key Features
- Dual comparator with push-pull output in a single 8-pin PDIP package
- Wide supply voltage range: 1.6 V to 5.5 V covering single-cell to dual-cell battery applications
- Ultra-low quiescent current of 1 µA per comparator for energy-constrained designs
- Rail-to-rail input range for maximum dynamic range at any supply voltage
- Max input offset voltage of 7 mV for reliable threshold detection in low-voltage systems
Applications
The MCP6542-E/P is commonly used in battery-powered portable devices for voltage threshold monitoring, power-good detection, and zero-crossing detection. It also fits industrial sensing circuits requiring dual comparator functionality on a 1.8 V or 3.3 V supply. Window comparator circuits and wake-up trigger applications in IoT edge nodes benefit from its low quiescent current.

Frequently Asked Questions
Can the MCP6542-E/P operate reliably from a single 1.8 V supply in a battery-powered IoT design?
Yes. The MCP6542-E/P is specified for supply voltages from 1.6 V to 5.5 V, so a 1.8 V single-cell or regulated rail is well within its operating range. Its quiescent current of 1 µA per comparator also keeps standby power extremely low.
How does the push-pull output of the MCP6542-E/P simplify interfacing compared to open-drain comparators?
With a push-pull output, the MCP6542-E/P actively drives both logic high and logic low, eliminating the external pull-up resistor needed by open-drain designs. This reduces BOM cost and board space, and speeds up output rise time in systems with 3.3 V or 5 V logic levels.
What is the maximum input offset voltage of the MCP6542-E/P and how does it affect threshold accuracy?
The MCP6542-E/P specifies a maximum input offset voltage of 7 mV. For a 1.6 V supply application, this 7 mV offset is roughly 0.4% of the full supply, so designers should budget this error into their threshold resistor divider calculations to maintain accurate trip points.
Is the MCP6542-E/P RoHS-compliant and lead-free for use in consumer electronics production?
Yes. Microchip codes the MCP6542-E/P as JESD-609 e3, confirming it is RoHS-compliant and lead-free. The 8-pin PDIP package uses a Pb-free finish suitable for standard reflow and wave soldering processes in consumer and industrial manufacturing.
