Product details

Threshold, timeout, and temperature range

The MAX6759UTTD0+: Reset timeout is 20 µs typical — the output remains asserted for this duration after the supply recovers above the threshold, giving the rail time to settle before the processor starts code execution. Operating temperature spans -40°C to +125°C, covering the industrial and automotive ambient range — the supervisor itself does not derate significantly across this band, but the threshold accuracy shifts with temperature per the datasheet typical curve.

SOT-23-6 footprint and supply posture

The SOT-23-6 package (supplier device package SOT-23-6) occupies a compact 2.9 mm × 1.6 mm footprint — the six pins accommodate the supply, ground, reset output, and a manual-reset input on the MAX6759 family, though this variant's specific pinout should be confirmed against the datasheet for the board layout.

Frequently asked questions

What is the MAX6759UTTD0+ used for?

It is a power supply monitor (voltage supervisor) that monitors a single 3.3V rail and asserts an active-low reset signal when the voltage drops below the threshold. It holds the reset output low for 20 µs after the supply recovers, ensuring the processor starts from a known state.

What is the output type of the MAX6759UTTD0+?

The reset output is active-low and open-drain (open collector). An external pull-up resistor is required to pull the output high when the supply is above the threshold.

What package does the MAX6759UTTD0+ come in?

It is supplied in a SOT-23-6 surface-mount package (supplier device package SOT-23-6), suitable for compact PCB layouts with standard reflow soldering.
