All rights reserved. is a registered trademark of Richtek Technology Corporation DS5509-00 August 2017 www.richtek.com 1 Speaker Amplifier with Speaker Protection General Description The RT5509 is a mono BTL class-D amplifier with cutting-edge speaker protection algorithm. Also, a built-in DC-DC step-up converter is used to provide efficient power for class-D amplifier. I2S interface supports two different audio sources while a pair of auxiliary DATAI/O is used for stereo mode or pass-through application. Chip information including gain, speaker protection output or current sense is able to be monitored via DATAO through proper register setting. Speaker protection provides mechanical / thermal protection with accuracy of 10%/±10 C of rated limit. Ordering Information RT5509 Package Type WSC : WL-CSP-48B 3.04x2.99 (BSC) Note : Richtek products are : RoHS compliant and compatible with the current requirements of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes.
