2.63V threshold, active-low supervisor in SC-70-3
The MAX6326XR26+T: Packaged in a 3-lead SC-70 (SOT-323), the part is a surface-mount supervisor that fits into dense, low-power designs where board space is the constraint. The single monitored voltage and push-pull output eliminate the need for an external pull-up resistor, simplifying the BOM.
Reset timing and output drive
The reset timeout is specified as 100ms minimum, which provides enough delay for most microcontrollers to exit their power-on reset state before the supervisor releases the reset line. The push-pull output can sink and source current directly, driving the reset input of an MCU or SoC without a pull-up resistor — a common oversight in board bring-up that this part avoids. The 2.63V threshold is a standard option for monitoring 2.5V or 3.0V rails, with a typical tolerance that ensures the reset asserts before the supply drops below the processor's minimum operating voltage. The SC-70-3 footprint is shared with other single-channel supervisors from the MAX6326 family, so a threshold change (e.g., to 2.93V or 3.08V) can be a drop-in replacement on the same PCB layout, provided the reset output type matches.
