Product details

Active-low reset, push-pull output

The reset output is active low — it goes low when the monitored voltage is out of tolerance. The push-pull stage can source and sink current, so it drives the reset input of an MCU or FPGA directly without a pull-up resistor. That saves one component per reset line. The output stays low until the supply is stable above the threshold, then releases high. No open-drain, no external resistor needed.

The SOT-23-3 package is surface-mount and reflow-compatible.

Frequently asked questions

Is MAX6378UR46+ active low or active high?

The reset output is active low — it goes low when the monitored voltage is below the threshold.
