Output circuit
This circuit uses the system to chop the lower power transistors and resurrect coil current through upper stage
diodes.
The upper-stage power transistor consists of Pch-MOS transistors (2SJ465), which give high torque efficiency.
Lower-stage pre drivers are supplied by VCC to reduce the power dissipation.
Triangular wave oscillator circuit
Triangular waves are generated by connecting a capacitor between the OSC pin and GND.
This circuit is current output type, which makes PWM signal by comparing its output current with control amp
output current.
fOSC[Hz] =
Taking in account efficiency considerations and the effects of noise, Toshiba recommends using the IC with an
oscillation frequency of 20kHz to 100kHz.
