Multi-voltage supervisor — active high reset, two-channel monitoring
The MAX6706MKA-T is a multi-voltage supervisor from Maxim Integrated that monitors two supply voltages: one fixed at 4.38 V and a second adjustable via an external resistor divider. The active-high reset output (push-pull, totem pole) asserts when either monitored voltage drops below its threshold and remains asserted for a minimum of 140 ms after all voltages rise above threshold. Operating across -40°C to 125°C, this part suits industrial and automotive environments where the system must survive under-hood or outdoor temperature swings without losing processor supervision.
