Product details

100ms timeout — why it matters for processor boot

The 100ms minimum reset timeout gives the power supply and oscillator time to settle before the processor starts executing code.

Package and mounting — SC-70-3 footprint

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. The push-pull output eliminates the need for an external pull-up resistor, saving one component on the board. Surface-mount only — no through-hole option exists for this part.

Lifecycle and sourcing reality

There is no end-of-life notice or last-time-buy window to manage. If you are qualifying this for a production build, the active status means you can design it in without planning a near-term replacement.

Frequently asked questions

What is the reset timeout of MAX6326XR24+T?

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.

Can MAX6326XR24+T be used with 2.5V systems?

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.

What is the closest pin-compatible alternative to MAX6326XR24+T?

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.

What is MAX6326XR24+T's listed type and reset polarity?

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.
