Product details

1.67 V threshold supervisor for low-voltage rails

The MAX6384XS17D3 is a single-channel voltage supervisor that monitors a 1.67 V supply rail and holds the system in reset until the rail stabilizes. It asserts a reset signal (active low, push-pull output) for a minimum of 140 ms after the voltage rises above the threshold. The part operates across -40°C to 125°C. The SC-70-4 package is a compact surface-mount footprint.

The 1.67 V threshold is the trip point — if the monitored supply drops below this level, the reset output goes low.

Frequently asked questions

What is the reset timeout of MAX6384XS17D3?

The reset timeout is 140 ms minimum. After the supply rises above the threshold, the reset output stays low for at least 140 ms before releasing.

Is MAX6384XS17D3 active low reset or active high?

The reset output is active low. When the monitored voltage is below the threshold, the output goes low.

What is the difference between MAX6384XS17D3 and MAX6385XS17D3?

The MAX6384XS17D3 has a push-pull output, while the MAX6385XS17D3 has an open-drain output. The push-pull version does not require an external pull-up resistor; the open-drain version does. Both share the same threshold and timeout.

What is the typical application for the MAX6384XS17D3?

Typical applications include monitoring low-voltage supply rails (e.g., 1.8 V) in microcontrollers, FPGAs, and digital signal processors to ensure a clean power-on reset in industrial, automotive, and telecom systems.
