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 175C, 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 175C, then the thermal shutdown (TSD) circuit is activated and the output circuit is will be mute. The TSD circuit is temperature hysteresis 25C. * 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].

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[F]. 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 x 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;

* 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.
