The SC-70-3 (SOT-323) package is a small three-lead surface-mount device. The supplier device package is SC-70-3, which means the PCB footprint matches the standard SC-70 land pattern. It is a manual-solder-friendly size for rework but small enough for dense layouts. Surface-mount only — no through-hole option exists for this part.
The reset timeout is 100ms minimum. That is the guaranteed hold time after the supply rises above the 2.4V threshold before the reset output releases. The actual timeout may be longer, but the minimum is 100ms.
Yes, the 2.4V threshold is designed for monitoring a 2.5V nominal supply rail. It asserts reset when the rail drops to 2.4V or below, giving about 100mV of margin below the nominal 2.5V before the processor is held off.
Within the MAX6326 family, other voltage threshold options (e.g., 1.6V, 2.2V, 2.6V, 2.9V, 3.1V, 4.4V) share the same SC-70-3 package and pinout, so you can change the monitored rail by swapping to a different threshold variant without a board layout change. Outside the Maxim family, parts like the TPS3823 or ADM809 offer similar simple reset functions in SC-70 but verify pin compatibility against the specific threshold and output type.
The listed type is Simple Reset/Power-On Reset. The reset output is active low with a push-pull, totem-pole output stage — no external pull-up resistor is needed.
