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. The host microprocessor
adopts I2C to control the switch position and read the
results of the accessory detection. The RT8966H can also
detect USB chargers, including dedicated chargers (D+/
Dshorted) and high, power, host/hub chargers.
The RT8966H has a linear charger with maximum 1A
current capability. The charging current and end of charge
current can be controlled by I2C interface. It also provides
a 50mA LDO to support the power of the peripheral circuit.
In factory mode, the RT8966H provides 4.35V/2.3A power
to support system operation.
The RT8966H is available in a thin WQFN-32L 4x4 package.
