Battery charge level indicator
Objective specification
SAA1501T
CHARACTERISTICS
V_CC = 3 V; T_amb = 25 °C; R_ref = 51.5 kΩ (0.1%); C_osc = 820 pF (0.1%); R_CCC = R_DCC = 3.65 kΩ (0.1%); R_max = 3.48 kΩ
(0.1%); I_ref = V_ref/R_ref; I_max = V_max/R_max; the minimum and maximum values are 4 sigma limits; unless otherwise
specified.
