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.

Because the thermal coefficient of V (Q) is −2mV / 1°C and if TR Q reaches 175°C from its normal off state
BE
(at 25°C), V for turning on Q becomes 400mV, and then Q turns on and the mute control circuit operates.

Vref is fixed to 2.5V as the external bias voltage and the input signal through the V is amplified to about 9.5dB through two
IN
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 + (I × V
) = V1 + ∆V
REF
) = V2 − ∆V
REF
C
V2’ = V2 − (I × V
C
Because V1 and V2 voltages, in their initial state, are equal, the voltage, V , on the sides of the motor is following V = V1’
M
M
− V2’ = ∆V − (−)∆V = 2∆V
Rotation occurs due to 2∆V voltage difference at both sides of the motor.

Notes:
: 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 V = 5V, CTL voltage should not be permitted to exceed 3V
CC
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.
