Application Information
1. REFERENCE INPUT & MUTE CIRCUITS Pin 23 can be used as a reference input terminal and a mute terminal. * Reference input circuit An external allowable reference voltage to pin 23 is normally 2.5V. In general conditions, pin 23 is used as the reference input terminal and is good to be used between about 2V-6.5V. * Mute circuit The following represents the conditions when the external mute is permitted to pin 23. Mute voltage Mute on voltage[V] Mute off voltage[V] Min. 2 Typ. Max. 0.5 Device condition Mute Operate
2. THERMAL SHUT-DOWN CIRCUIT
VREF BG
R1 Q R2
Mute control
The setting voltage of VBE VBE = VREF BG x R2 / (R1 + R2) = 400mV Because the thermal coefficient of VBE(Q) is -2mV / 1C and if TR Q reaches 175C from its normal off state (at 25C), VBE for turning on Q becomes 400mV, and then Q turns on and the mute control circuit operates.

LEVEL SHIFTER
GV1 +-
VREF (pin 23) VIN
GV = 20log (VO/VIN) = GV1 + GV2 = 3.5dB + 6dB = 9.5dB Vref is fixed to 2.5V as the external bias voltage and the input signal through the VIN is amplified to about 9.5dB through two state AMP. In the level shift circuitry, the input signal is transformed into the current so that the voltage V1 and V2 are shifted to V1' and V2' respectively. V1' = V1 + (IC x VREF) = V1 + V V2' = V2 - (IC x VREF) = V2 - V Because V1 and V2 voltages, in their initial state, are equal, the voltage, VM, on the sides of the motor is following VM = V1' - V2' = V - (-)V = 2V Rotation occurs due to 2V voltage difference at both sides of the motor.

Notes: VCTL: When the motor speed control voltage is permitted between 0V ~ 4V, the motor varies its speed. Between 4V ~ 5V, the motor can be used at constant speed and over 5.8V, the motor should not be used. Furthermore, when VCC = 5V, CTL voltage should not be permitted to exceed 3V
The logic signals, input from the MCU, is inverted in the inverter and can control the changes of the output properties, that depend on the input signal.
