CTL amplifier + (no inverting) input. The
PWMIN pin must be held at the low level to
use this input for motor control.
Stabilizing supply output pin. (5V output)
Connect a capacitor between this pin and
ground for stabilization. (about 0.1μF level)
Power supply. Connect a capacitor between
this pin and ground to prevent noise and
other disturbances from affecting this IC.
Ground
Output current sensing pin.
The low resistance is connected between RF
and GND. It sets it by output maximum
current IOUT=0.25/Rf.
Output pin. (Driving external TR output)
The duty is controlled on UH, VH, and WH
side.
