Product details

Supervisor IC for 2.63V rails — what the threshold means for your processor

The MCP102T-270E/LB is a single-channel voltage supervisor from Microchip that asserts a reset signal when the monitored supply drops below 2.63V. The reset output is Active Low and push-pull (totem pole), so it drives the reset pin of most MCUs and SoCs directly without an external pull-up resistor. The SC-70-3 package fits tight layouts where board area is the constraint.

The 2.63V threshold is a common choice for 3.3V logic rails — it trips before the supply falls below the minimum operating voltage of most 3.3V processors.

The SC-70-3 package is widely stocked across the supply chain.

Frequently asked questions

Is MCP102T-270E/LB active low reset?

Yes, the reset output is Active Low. It pulls low when the supply drops below the threshold and releases high after the 80 ms timeout once the supply recovers.

What package does MCP102T-270E/LB come in?

It comes in an SC-70-3 (SOT-323) surface-mount package. The supplier device package is SC-70-3.

What is the reset timeout of MCP102T-270E/LB?

The reset timeout is a minimum of 80 ms. This is the period the output stays asserted after the supply rises above the threshold.
