Product details

What the MAX6729AKASYD3+ is and where it fits

The MAX6729AKASYD3+ from Maxim Integrated is a multi-voltage supervisor that monitors two supply rails with thresholds at 2.188V and 2.925V. It asserts an active-low reset output (push-pull, totem pole) when either monitored voltage falls below its threshold, and holds reset for a minimum of 140ms after all voltages recover. This part is AEC-Q100 qualified for automotive applications, with an operating temperature range of -40°C to +125°C, making it suitable for under-hood and engine-bay environments where extended temperature and reliability screening are required. The SOT-23-8 package keeps board area small for space-constrained ECU or sensor-module designs.

Lifecycle and sourcing reality

For a BOM line that needs automotive-grade supervision, this part is a safe choice for new designs and ongoing production.

Frequently asked questions

Does the MAX6729AKASYD3+ work with a 3.3V microcontroller?

Yes. One of its monitored thresholds is 2.925V, which is appropriate for a 3.3V supply rail. The active-low reset output is push-pull, so it connects directly to a typical MCU reset pin without an external pull-up.

What is the reset timeout duration for MAX6729AKASYD3+?

The reset timeout is a minimum of 140ms. After all monitored voltages rise above their thresholds, the reset output stays asserted for at least 140ms before releasing the processor.
