Thermal Shut-down Circuit VREF BG R1 Mute control Q 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. 3.

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.

Loading, Changer Drive Circuits M OUT1 OUT2 D D LEVEL SHIFT VCTL SPEED CONTROL LOGIC IN IN VIN1 VIN2 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.
