The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VCC = 5V, GND = 0V and VBAT is equal to the float voltage unless
otherwise noted. All currents into device pins are positive. All currents out of device pins are negative. All voltages are referenced to
GND, unless otherwise specified.
