(1) All voltages are with respect to the potential at the SGND pin.
(2) Min and Max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the
most likely norm. Unless otherwise specified, conditions for typ. specifications are: V_BATT = 3.6V and T_A = 25°C.
