- Mute function using the MUTE and BRAKE pin (Channel mute)

Mute function for each channels can be obtained using the MUTE pin (pin19,pin21) and BRAKE pin (pin23).
* When the voltage of the pin19 becomes low , the bias currents for CH3,CH4 are shut down and those
corresponding channels are muted. On the contrary, when the voltage of the pin19 becomes high, the channel
drivers operate normally.
* When the voltage of the pin21,23 become high , the bias currents for CH1,CH2 are shut down and those
corresponding channels are muted. On the contrary, when the voltage of the pin21,23 become low, the channel
drivers operate normally.

- All mute function using the REF pin (Reference all mute)

Muting all channel drivers can be obtained using the REF (signal reference) pin.
* When the input voltage of the signal reference pin (pin16) is below 1.0V, the bias currents of all channel
drivers are shut down.

* R is an external resistor which is connected to input pins (pin17,18,20,22)

- Power supply voltage

IP9001 has two kinds of power supply pins. One is power supply for output stage(pin36), the others are
signal power supply for pre driver(pin12, pin15). All power supply pins should be attached by-pass capacitor
with each other.

APPLICATION SUMMARY (Continued)

Power supply driving circuit detects a maximum output voltage among the 4-CH output pins, and then
control external PNP TR to reduce the power consumption.
This buck converter consists of external PNP TR, Schottky barrier diode, Inductor, and capacitors.

When the sensing voltage of SENS(pin1) falls below detecting voltage, then EMP(pin35) goes from High
level to low level. The detector voltage has 50mV hysteresis.
According to the SEL(pin42) voltage level, the detector voltage varies as following table,

IP9001 has a charging circuit and it is independent from any other circuit.
Its power supply pin is CHGVCC which is directly connected to adapter.
Battery charging current is controlled by changing RCHG (between RCHG(pin33) and GND).
It also has an independent TSD circuit which has shut down temperature of 175

C and the hysteresis

temperature is 25
