RT9535B High Efficiency Switching Mode Battery Charger General Description The RT9535B is a PWM switch mode battery charger controller to fast charge single or multiple Li-Ion, NiMH and NiCd batteries, using constant current or constant voltage control. Maximum current can be easily programmed by external resistor. The constant voltage output can support up to 22V with 0.5% accuracy. A third control loop limits the input current drawing from the adapter during charging. This allows simultaneous operation of the equipment and fast battery charging without over loading to the adapter. The RT9535B can charge batteries from 2.5V to 22V with dropout voltage as low as 0.4V. A logic output indicates Li-Ion full charge when current drops to 17% of the full-scale programmed charge current.
