Frequently Asked Questions
What is the exact threshold voltage range of the MCP111T-240E/LB, and how tight is the detection accuracy?
The MCP111T-240E/LB detects a supply falling between 2.262 V and 2.378 V, corresponding to a nominal 2.4 V trip threshold with approximately ±2.4% accuracy. This tight band ensures that the active-low RESET output asserts reliably before the monitored 2.5 V or 3.3 V logic rail drops below safe operating limits for the MCU.
How does the SC-70-3 package of MCP111T-240E/LB compare to SOT-23-3 for ultra-compact board designs?
The MCP111T-240E/LB uses an SC-70-3 package, which has a body size of approximately 2 mm x 1.25 mm — notably smaller than the SOT-23-3 at 3 mm x 1.75 mm. This extra space savings is valuable in wearable devices, hearing aids, and miniature IoT sensors where every square millimeter of PCB area counts.
What is the lead time for MCP111T-240E/LB, and should engineers carry safety stock for this part?
The MCP111T-240E/LB has a factory lead time of 7 weeks. For production schedules relying on this 3-pin SC-70 voltage supervisor, procurement teams should plan safety stock of at least 4 to 6 weeks of consumption to buffer against demand spikes, especially for high-volume IoT device builds.
Can the MCP111T-240E/LB supervise a 3.3 V supply rail in an MCU system without any additional external components?
The MCP111T-240E/LB is designed as a standalone supervisor requiring no external resistors or capacitors for basic operation; it monitors the supply pin directly and drives its open-drain RESET pin low when VCC falls below 2.4 V. However, since its trip threshold is 2.4 V, it is better suited to supervise a 2.5 V or lower rail rather than a 3.3 V rail without additional level shifting.
