MAX14778 datasheet(4/16 Pages) MAXIM

(VDD = 3.0V to 5.5V, TA = -40°C to +125°C, unless otherwise noted. Typical values are at VDD = 5V, TA = +25°C.) (Note 1)

Note 1: All units are production tested at TA = +25°C. Specifications over temperature are guaranteed by design.

Note 2: 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 3: 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.
