Product details

The MAX6844UKD3+: The reset output stays asserted for a minimum of 140 ms after the supply returns above the threshold, giving the downstream microcontroller or logic time to stabilize before the processor starts executing code. The output is push-pull, totem-pole, so it drives the reset line directly without requiring an external pull-up resistor — a clean connection to the MCU reset pin.

Package, footprint, and temperature range

Housed in a 5-pin SOT-23-5 package (also designated SC-74A, SOT-753), the MAX6844UKD3+ occupies a board footprint of roughly 3.0 mm × 3.0 mm. The surface-mount package is suited for reflow assembly and fits into space-constrained designs like portable instruments, sensor nodes, or industrial control modules.

Frequently asked questions

What does the active-high reset output mean for my circuit?

An active-high reset means the output pin goes high (to the supply voltage) when the monitored voltage is within tolerance, and pulls low when a reset condition is triggered. This is the opposite of the more common active-low reset. If your microcontroller expects a low-true reset signal, you would need an inverter or a different part — check the reset polarity before specifying.
