Rail supervision with a 2.93V threshold
The MAX6805US29D3+T: The Active Low, Open Drain output pulls low during reset and requires an external pull-up resistor to the monitored rail or the logic supply — a standard interface for most MCU and DSP reset inputs. With a minimum reset timeout of 100ms, the part provides enough debounce to ignore short supply glitches while ensuring the system holds in reset long enough for the power rail to stabilize.
Industrial temperature range and small package
Housed in a SOT-143-4 package (TO-253-4 equivalent), the part occupies minimal board area and is a surface-mount fit for dense PCB layouts where every square millimeter counts.
