3 / 20 page ![]() 3 LTC4060 4060f SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS The ● indicates specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 5V, VBAT = 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.
