Application Information
1. REFERENCE INPUT
Pin 45 (REF) can use the reference Input pin .
• Reference input
In the case of the reference input pin, you must keep the applied voltage range between 2[V] and 6.5[V] at VCC = 8[V].
2. SEPARATED CHANNEL MUTE FUNCTION
These pins are used for individual channel mute operation.
• When the mute pins (pin19, 20, 21 and 22) are high level, the mute circuits are activated so that the output circuit is muted.
• When the voltage of the mute pins (pin19, 20, 21 and 22) are low level, the mute circuit is stopped and output circuits
operate normally.
• If the chip temperature rises above 175°C, then the thermal shutdown (TSD) circuit is activated and the output circuits are
muted.
- Mute 1 (pin 19)-CH1 mute control input pin.
- Mute 2 (pin 20)-CH2 mute control input pin.
- Mute 3 (pin 21)-CH3 mute control input pin.
- Mute 4 (pin 22)-CH4 mute control input pin.
3. PROTECTION FUNCTION
• Thermal shutdown (TSD)
If the chip temperature rises above 175°C, then the thermal shutdown (TSD) circuit is activated and the output circuit is will
be mute. The TSD circuit is temperature hysteresis 25°C.
• Under voltage lockout (UVLO) and over voltage protection (OVP)
It is designed to mute-operate the internal bias by the function of UVLO and OVP, when the power supply voltage falls
below 3.5[V] or above 20[V].
13
FAN8033
4. REGULATOR & RESET FUNCTION
The regulator and reset circuits are as illustrated in Figure 1.
where R1=R2.
• The external circuit is composed of the transistor, KSB772 and a capacitor, about 33[µF]. The capacitor is used as a ripple
eliminator and should have good temperature characteristics.
• The regulator output voltage (pin 46) is decided as follows.
Vout = 2 × 2.5 = 5[V] (where R1 = R2)
• When the voltage of pin 43 (Vreset) is at 5[V], the regulator output voltage (pin 46) because 5[V]. If the voltage
of pin 43 is 0[V], the output voltage of pin 46 because 0[V].

• The voltage, Vref is the reference voltage given by the external bias voltage of the pin 45.
• The input signal (Vin) through pins 3, 6, 9 and 48 is amplified one times (Rref1 = Rfeed1) by the AP1 and then fed to the
level shift.
• The level shift produces the current due to the difference between the input signal and the arbitrary reference signal. The
current produced as +∆I and −∆I are fed into the output amplifier, where output amplifier (AP2, 3) gain is two times (all
Rref2 = Rfeed2).
• If you desire to change the gain, the input buffer amplifier (BF) can be used.
• The output stage is the balanced transformerless (BTL) driver.
• The bias voltage Vr is expressed as below;

Vr = ---------------------------- [ V ]

• Rotational direction control

• where Vr is (Vcc - Vbe) / 2 = 3.65V (at Vcc=8V)
• where Out1 pins are pins 24 and 26, and out2 pins aer pins 25 and 27
• Motor speed control
- The almost maximum torque is obtained when it is used with the pins 12 and 15 (CTL1, 2) open.
- If the torque of the motor is too low, then the applied voltage at pins 12 and 15 (CTL1, 2) are 0[V].
- When motor speed controlled, the applied voltage of the pins 12 and 15 (CTL1, 2) is between 0 and 4V.
Also, if the speed control is constant, the applied voltage of the pins 12 and 15 (CTL1, 2) is between 4 and 5V.
- This IC's applied maximum voltage is 6V when VCC is 8V.
- You must not use the applied CTL1, 2 voltage above 5.8V when VCC is 8V, and 3V when VCC is 5V.
