RT9535

High Efficiency Switching Mode Battery Charger

General Description

Features

The RT9535 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.

 Fast Charging for Li-Ion, NiMH and NiCd Batteries

 Adjustable Battery Voltages from 2.5V to 22V

 High Efficiency : Up to 95%

 Charging Current Programmed by Resistor

 Precision 0.5% Charging Voltage Accuracy

 Provide 5% Charging Current Accuracy

 Input Current Limit Maximizes Charging Rate

 500kHz Switching Frequency

 Flag Indicates Li-Ion Charge Completion

 Auto Shutdown with Adapter Removal

 Only 10A Battery Reverse Current when Idle

The RT9535 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.

The RT9535 is available in the WQFN-24L 4x4

package.
