ELECTRICAL CHARACTERISTICS (continued)

(VCC = +2.5V to +5.5V for the MAX6305/MAX6308/MAX6311, VCC = (VTH + 2.5%) to +5.5V for the MAX6306/MAX6307/MAX6309/

MAX6310/MAX6312/MAX6313; TA = 0°C to +70°C; unless otherwise noted. Typical values are at TA = +25°C.)

Note 1: The MAX6305/MAX6308/MAX6311 switch from undervoltage reset to normal operation between 1.5V < VCC < 2.5V.

Note 2: The MAX6306/MAX6307/MAX6309/MAX6310/MAX6312/MAX6313 monitor VCC 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).
