Description
Motor output B, Motor current flows from M
Clock oscillator. Timing pin connect a 56 k resistor and a 820 pF in
parallel between T and Ground.
Motor supply voltage, 10 to 45 V. V
PCB.
Ground and negative supply. Note these pins are used for heatsinking.
Make sure that all ground pins are soldered onto a suitable large copper
ground plane for efficient heat sinking.
Logic voltage supply normally +5 V.
Logic input, it controls, together with the I
output stage. The controllable levels are fixed to 100, 60, 20, 0%.
Controls the direction of the motor current of M
current flows from M
Logic input, it controls, together with the I
output
Comparator input. This input senses the instantaneous voltage across the
sensing resistor, filtered through a RC Network.
Reference voltage. Controls the threshold voltage of the comparator and
hence the output current. Input resistance: typically 6.8k
Motor output A, Motor current flows from M
Common emitter. Connect the sense resistor between this pin and ground.
