with Accessory detection and OVP
http://onsemi.com
Overview
The LC824204-13YB is the IC suitable for use in multi function and high performance switch as well as compatible
accessory detector which supports micro USB connector for DSC, DVC and mobile phone.
This IC includes low impedance USB supply switch (100 mΩ) which enables high speed battery charge as well as
USB2.0-capable switch with low input capacitance, negative input-capable low distortion audio switch, UART,
microphone (Mono, Stereo), and various video signal switches.
Also, this IC integrates auto detector for accessories which is capable of detecting accessories compliant to CEA936-A
automotive kit and ACA standard which includes MCPC standard established in June 2010. In addition, it’s capable of
detecting a lot of charger accessories, such as Dedicated (D+/D- short) charger, Apple charger, SONY charger, USB
charger and so on. Switching operation is controlled via I²C serial interface.
