The RT9535A 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 RT9535A can charge batteries from 2.5V to 22V with dropout voltage as low as 0.4V.
The RT9535A is available in the WQFN-16L 4X4 package.
