What are the key features of MCP6542-I/SN?

  • Dual comparator with push-pull output for direct logic interfacing
  • Ultra-low 0.1 nA maximum input bias current
  • Wide supply range from 1.8V to 5.5V
  • No pull-up resistor required due to push-pull output stage
  • 8-pin SOIC package with standard 3.9mm body width
  • 7 mV maximum input offset voltage for threshold accuracy

What is MCP6542-I/SN used for?

MCP6542-I/SN is used in battery management circuits, window detector thresholds, and low-power wake-up circuits where its push-pull output eliminates the pull-up resistor required by open-drain comparators, saving components and power. Its ultra-low 0.1 nA bias current makes it ideal for voltage monitoring in high-impedance battery cell balancing and supercapacitor management systems. The dual-channel configuration in a single SOIC-8 package handles two independent threshold comparisons such as over-voltage and under-voltage lockout in a compact BMS front-end.

Frequently Asked Questions

How does MCP6542-I/SN's push-pull output differ from open-drain comparators, and what design benefit does this provide?

MCP6542-I/SN's push-pull output actively drives both logic high and logic low states without requiring an external pull-up resistor. Open-drain comparators need a pull-up resistor typically valued from 10 kΩ to 100 kΩ, which consumes static current; eliminating it reduces standby power by up to 500 µA on a 5V rail, a meaningful saving in always-on battery monitoring applications.

What is the input bias current of MCP6542-I/SN, and how does this impact high-impedance threshold detector designs?

MCP6542-I/SN specifies a maximum input bias current of 0.1 nA (100 pA), allowing use of resistor divider networks up to 10 MΩ without introducing more than 1 mV of threshold error. This enables battery voltage dividers with sub-microamp quiescent current in IoT nodes and medical implant monitors where every nanoamp matters.

Can MCP6542-I/SN be used in a 3.3V microcontroller system, and what supply voltage does it require?

Yes. MCP6542-I/SN operates from 1.8V to 5.5V, so it runs directly from a 3.3V rail with full push-pull output swing from 0V to 3.3V, providing clean TTL-compatible logic levels to a microcontroller GPIO without any level-shifting. The same part also works in 5V analog systems, covering a broad range of embedded designs with a single stock item.
