REFERENCE INPUT & MUTE Pin 46 (REF) uses the reference input pin or the all mute input pin a reference input block circuit. • Reference input In the case of external reference input, the applied voltage range must be between 2[V] and 6.5[V] at VCC=8[V]. • All mute input Using the all mute function pin, the applied voltage condition is as follows. All mute on voltage Below 0.5[V] Mute function operation All mute off voltage Above 2.0[V] Normal operation 2. SEPARATED CHANNEL MUTE FUNCTION These pins are used for the individual channel mute operation. • When the mute pins (pin22, 23 and 24) are high level, the mute circuits are activated so that the output circuit is muted. • When the voltage of the mute pins (pin22, 23 and 24) 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, 2 (pin 24)-CH1, 2 mute control input pin. - Mute 3 (pin 23)-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 mute. The TSD circuit is temperature hysteresis about 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 KA3032 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 41) is decided as follows. Vout = 2 × 2.5 = 5[V] (where R1=R2) • When the voltage of pin 44 (Vreset) is at 5[V], regulator output voltage(pin 41) is 5[V], and if 0[V], the output voltage of pin 41 is 0[V].

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; V CC – V BE Vr = ---------------------------- [ V ] 2 15 KA3032 6.

Conditions are as follows. INPUT OUTPUT FWD REV OUT 1 OUT 2 H H Vr Vr Brake H L H L Forward L H L H Reverse L L Vr Vr Brake . where Vr is (Vcc - Vbe) / 2 = 3.65V (at Vcc=8V) where Out1 pins are pins 24 and 26, and out2 pins are pins 25 and 27 • Motor Speed Control - The almost maximum torque is obtained when it is used with the pins 13 (CTL) open. - If the torque of the motor is too low, then the applied voltage at pins 13 (CTL) is 0[V]. - When motor speed controlled, the applied voltage of the pins 13 (CTL) is between 0 and 4V. Also, if speed control is constant , the applied voltage of the pins 13 (CTL) is between 4 and 5V. - This IC's applied maximum voltage is 6V when VCC is 8V. - You must not use the applied CTL voltage above 5.8V when Vcc is 8V, and 3V when VCC is 5V. 16 State KA3032 Typical Performance Characteristics Total circuit Icc(mA) Icc(mA) <Vcc vs Icc> 14 <Temp vs Icc> 13.4 13.2 13.5 13.0 12.8 13 12.6 12.5 12.4 12.2 12 12.0 11.8 Vcc=Var.
