Function
11
Not wired
Connect all power ground pins and V
The pin functions as a heat sink. Design pattern
taking heat into consideration.
Connect all power ground pins to GND.
Not wired
H: Controls external PWM.
L: CLK-IN mode
We recommend this pin normally be used as
CLK-IN mode pin (Low).
In PWM mode, functions such as constant
current control do not operate.
Forcibly initializes electrical angle.
At this time we recommend ENABLE pin be set
to Low to prevent misoperation.
H: Resets electrical angle.
L: Normal operation
Forcibly turns all output transistors off.
Electrical angle is incremented by one for each
CLK input.
CLK is reflected at rising edge.
Determines chopping frequency.
