Note 1: Overtemperature limits are guaranteed by design, not production tested.
Note 2: The MAX6305/MAX6308/MAX6311 switch from undervoltage reset to normal operation between 1.5V < V
CC
< 2.5V.
Note 3: The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/MAX6313 monitor V
CC
through an internal factory-trimmed voltage
divider, which programs the nominal reset threshold. Factory-trimmed reset thresholds are available in approximately
100mV increments from 2.5V to 5V (Table 1).
Note 4: Guaranteed by design.
