® RT8966H Mini Analog Baseband Power Management IC General Description The RT8966H is an analog subsystem which includes a linear charger, 4 LDOs, a 4-CH current source, and a multiplexer for USB, UART, microphone, stereo and audio on a single mini/micro USB connector. The RT8966H adopts an I2C bus for control and uses an internal method to determine the connected device. The USB input provides high speed USB connection. The audio inputs feature negative rail signal operation to realize simple DC coupled headset speakers. The RT8966H provides an internal device detection method by using the USB ID signal pin and the VBUS voltage. The resistor values and VBUS voltage determine the unique detection method of each accessory.
