Description
O _{H bridge channel 2 output A}
O _{H bridge channel 2 output B}
Power source for control logic
I Set mode brake function for channel 1~4
O
1.2 V, this is a input voltage for resistors divider to generate the VC6
voltage
O
The voltage of VOUT5A, VOUT5B is four times large as VC5, output
will be saturated once the VC5=VDD

H bridge channel 6 power source
O H bridge channel 6 output A
I
Channel 6 motor drive current sense, connect a resistor between
this terminal and GND
O H bridge channel 6 output B
I Channel 6 comparator input
I Channel 6 comparator adjustable input
Control logic GND
H bridge channel 3,4 power GND
