Note 2: All units are production tested at TA = +25NC. Specifications over temperature are guaranteed by design.
Note 3: When VDD is higher than the charge-pump threshold, the internal 5V regulated charge pump is turned off and the input to
the high-voltage charge pumps is provided by VDD.
Note 4: The MAX14778 requires a 100nF capacitor on both VP and VN to GND to guarantee full ESD protection. See the
Applications Information section for details on ESD test conditions.
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.0V to 5.5V, TA = -40NC to +85NC, unless otherwise noted. Typical values are at VDD = 5V, TA = +25NC.) (Note 2)
