Overview

® RT9531 High Efficiency Switching Mode Battery Charger General Description The RT9531 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 adjusted by external resistor.
The constant voltage output can support up to 4 Li-Ion cells 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 RT9531 can charge batteries from 2.
5V to 4.
2V with dropout voltage as low as 0.
4V.
A diode is n...
