Constant-current charging circuit composed of the MIC5158 is as shown. In the whole process of charging, the circuit provides a constant current (35 mV/R3), until the battery voltage is charged to Vfl:. Vfl is float charge voltage (V). When float voltage is satisfied, MOSFET tube was turned off, and the R4 provides access forthe charge current.
