ELECTRICAL CHARACTERISTICS The ● indicates specifications which apply over the full operating
temperature range, otherwise specifications are at T A = 25 ° C. V CC = 5V, V BAT = 2.8V, GND = 0V unless otherwise specified. All
currents into the device pins are positive and all currents out of the device pins are negative. All voltages are referenced to GND
unless otherwise specified.
