Frequently Asked Questions
How does the integrated 2.4 V reference in MCP65R46T-2402E/CHY simplify battery monitoring circuit design?
The integrated 2.4 V reference in the MCP65R46T-2402E/CHY eliminates the need for an external voltage reference IC, reducing component count by at least 2 parts. This simplifies PCB layout for battery undervoltage detection, allowing a direct resistor-divider from the battery to the comparator input to set the trip threshold relative to the stable 2.4 V reference.
At what supply current does MCP65R46T-2402E/CHY operate, making it suitable for always-on IoT monitoring?
The MCP65R46T-2402E/CHY draws only 3 µA of quiescent current from a 1.8 V to 5.5 V supply, making it one of the lowest-power comparators with an integrated reference. In a coin-cell-powered IoT node, this allows continuous threshold monitoring for years without replacing the battery, compared to standard comparators consuming 50 µA or more.
How should the open-drain output of MCP65R46T-2402E/CHY be connected to a 3.3 V microcontroller interrupt pin?
Connect a 100 kΩ pull-up resistor from the 3.3 V rail to the open-drain output pin of MCP65R46T-2402E/CHY, then wire the output directly to the microcontroller interrupt pin. When the comparator triggers, the output pulls low, generating an active-low interrupt. Multiple MCP65R46T outputs can share one pull-up in a wired-OR alarm configuration.
What response time does MCP65R46T-2402E/CHY offer, and is it fast enough for overcurrent protection?
The MCP65R46T-2402E/CHY has a propagation delay of 0.85 µs, which is sufficient for overcurrent protection in circuits where the fault current rises over microseconds. For very fast fault events below 100 ns, a dedicated high-speed comparator would be preferred, but for battery and power-management overcurrent detection, the 0.85 µs response time is more than adequate.
