Product details

What this reset supervisor does

The Maxim Integrated MAX6832VXRD3 is a single-channel voltage supervisor that monitors a 1.575V rail and asserts a reset signal when the supply drops below that threshold. The output is active-low, push-pull, so it drives the reset line high or low without needing an external pull-up resistor. The reset timeout is a minimum of 140ms, giving the system time to stabilize before the processor starts executing code.

Package and mounting

Housed in an SC-70-3 (SOT-323) surface-mount package, the MAX6832VXRD3 takes up minimal board area—three pins, no thermal pad to worry about. The SC-70 footprint is common for small supervisory ICs, so layout reuse across designs is straightforward.

Temperature range and environment

Rated for -40°C to 85°C ambient, this part suits industrial control, telecom base stations, and outdoor equipment where the board sees seasonal temperature swings but not extended under-hood heat. The industrial temperature grade covers most embedded applications outside of automotive or downhole environments.

Frequently asked questions

What does the 1.575V threshold mean for my design?

The 1.575V threshold is set to monitor a 1.5V or 1.8V nominal supply rail—common for DDR memory or low-voltage core logic. The reset asserts when the monitored voltage falls below 1.575V, which provides a clean power-fail or brown-out indication before the logic becomes unreliable.
