Package and integration footprint
The MAX6730AUTTD3+T is a single-channel voltage supervisor in a SOT-23-6 package (supplier device package SOT-6). The 3.075 V threshold suits 3.3 V rails where a clean power-up sequence is critical — the 140 ms minimum reset timeout holds the reset line low long enough for the downstream MCU or FPGA to stabilise before release. The active-low, open-drain output lets multiple supervisors share a common pull-up resistor on the reset bus — a standard configuration in multi-rail systems where each rail needs independent monitoring.
The SOT-23-6 package's thermal impedance is low enough that self-heating from the 5 µA typical supply current is negligible, so the ambient rating is the effective operating limit.
