Mute control

R2
The setting voltage of VBE
VBE = VREF BG × R2 / (R1 + R2) = 400mV
Because the thermal coefficient of VBE(Q) is −2mV / 1°C and if TR Q reaches 175°C from its normal off state
(at 25°C), VBE for turning on Q becomes 400mV, and then Q turns on and the mute control circuit operates.

(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 × VREF) = V1 + ∆V
V2’ = V2 − (IC × 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 = 2∆V
Rotation occurs due to 2∆V 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 rotates at constant speed and over 5.8V, the motor should be shut off.
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. There properties are shown in the table below.
