Frequently Asked Questions
What reset threshold voltage does the MCP102T-300E/TT enforce for 3.3 V systems?
The MCP102T-300E/TT is factory-trimmed to assert a reset when the monitored supply falls below approximately 2.93 V (nominal threshold within the 2.857 V to 3.003 V window), making it well-suited for 3.3 V rail supervision in embedded designs with at least 20 mV of hysteresis.
How does the 3-pin SOT-23B package influence PCB layout for the MCP102T-300E/TT?
With only 3 pins in the SOT-23B package, the MCP102T-300E/TT occupies minimal board space, typically under 3 mm x 3 mm footprint, allowing designers to place it immediately adjacent to the microcontroller VCC pin without routing concerns or bulky passive components.
Is MCP102T-300E/TT suitable for designs that require RoHS-compliant components?
Yes, the MCP102T-300E/TT carries a Pb-free code of Yes and a JESD-609 code of e3, confirming full RoHS compliance. This makes it appropriate for consumer electronics, industrial controls, and other end products subject to EU RoHS and WEEE directives.
When should a designer choose MCP102T-300E/TT over a programmable threshold voltage supervisor?
MCP102T-300E/TT is the right choice when the target supply is a fixed 3.3 V rail and BOM simplicity matters; the factory-trimmed threshold (2.857 V to 3.003 V) eliminates 2 external resistors and reduces layout area compared to adjustable-threshold supervisors requiring resistor dividers.
