DESCRIPTION
driver output 1
test input/output
not connected
driver output 2
input voltage for the output driver stages
position generator: input from the position detector sensor to the position
detector stage (optional); only if an external position coil is used
position generator/frequency generator: output of the rotation speed and position
detector stages (open collector digital output, negative-going edge is valid)
ground supply return for control circuits
positive supply voltage
external capacitor connection for adaptive communication delay timing
external capacitor connection for adaptive communication delay timing copy
external capacitor connection for start-up oscillator
external capacitor connection for timing
non-inverting input of the transconductance amplifier
inverting input of the transconductance amplifier
transconductance amplifier output (open collector)
driver output 3
not connected
input from the star point of the motor coils
ground (0 V) motor supply return for output stages
