Typical Charge Cycle
Evaluation Board congured for internal timer, 1.5V on IPRGM = 843mA, 1.5V on ITERM = 300mA, VCC = 5.0V, Li-Ion
battery capacity = 850mAh. A 237Ω load resistor (18mA at a battery voltage of 4.36V) was applied to the battery fol-
lowing completion of precharge, to slowly discharge the battery following charge timer timeout to illustrate a recharge
cycle. The alphabetic markers indicate the following: (a) precharge; (b) fast charge, or Constant Current (CC) charg-
ing; (c) Constant Voltage (CV) charging; (d) termination; (e) CV (“oat”) charging until charge timer timeout; (f) charge
timer timeout; (g) discharge of the battery due to 18mA load; (h) recharge cycle initiated when battery voltage drops
below the recharge threshold.
