Electrical Characteristics
All limits are guaranteed. The parameters with min and max
values are guaranteed with production tests or SQC (Statistical
Quality Control) methods.
V_VIN = +2.5V to +4.8V, T_AMB = -30ºC to +85ºC, unless otherwise
specified. Typical values are at V_BAT = +3.7V, T_AMB = +25ºC,
unless otherwise specified.
