Key Features
- 1.6V minimum supply voltage enables operation in ultra-low-voltage battery-powered and energy-harvesting applications
- Open-drain output with chip select allows direct connection to I2C-like bus structures and wire-OR logic configurations
- 100pA maximum input bias current minimizes loading on high-impedance sensor and signal sources in precision detection circuits
- 8-pin MSOP compact package reduces PCB footprint in space-constrained portable and wearable device designs
Applications
The MCP6548-I/MS is used in battery-powered devices, wearable sensors, and portable instrumentation where an ultra-low-voltage comparator is needed for threshold detection, window comparison, or zero-crossing detection. Its open-drain output with chip select is well-suited for multi-channel comparison systems that share a common output bus, such as battery cell monitoring and over-temperature alert circuits. The low 1.6V operating voltage makes it compatible with single-cell lithium-ion, NiMH, and other low-voltage energy sources.

Frequently Asked Questions
What is the minimum supply voltage for the MCP6548-I/MS?
The MCP6548-I/MS operates from a minimum supply voltage of 1.6V, making it suitable for single-cell battery systems, energy harvesting circuits, and low-voltage microcontroller applications where supply rails are constrained to below 2V.
What type of output does the MCP6548-I/MS use?
The MCP6548-I/MS has an open-drain output configuration. This allows multiple comparator outputs to be wire-OR'd together on a shared bus or connected to I2C-compatible logic without additional output driver circuitry, simplifying multi-comparator system designs.
What is the input offset voltage of the MCP6548-I/MS?
The MCP6548-I/MS has a maximum input offset voltage of 7000µV (7mV). While not a precision comparator, this offset is acceptable for threshold detection, level crossing, and window comparator applications where precise voltage thresholds are set externally.
What package is the MCP6548-I/MS available in?
The MCP6548-I/MS is packaged in an 8-pin MSOP (Mini Small Outline Package, JEDEC S-PDSO-G8). This compact surface-mount package is suitable for space-constrained PCB designs in portable electronics, wearables, and handheld instruments.
What is the input bias current of the MCP6548-I/MS?
The MCP6548-I/MS has a maximum average input bias current of 100pA (0.0001µA). This extremely low bias current minimizes the error voltage developed across high-impedance source resistances, making the comparator compatible with sensors and signal sources with output impedances in the megaohm range.
