Description
Motor output A, channel 1. Motor current flows from MA1 to MB1 when Phase1 is high.
Motor output A, channel 2. Motor current flows from MA2 to MB2 when Phase2 is high.
Common emitter, channel 2. Connect the Sense resistor between this pin and ground.
Comparator input, channel 2. This input senses the instantaneous voltage across the sensing
resistor, filtered through a RC network.
Motor output B, channel 2. Motor current flows from MA2 to MB2 when Phase2 is high.
Ground and negative supply. These pins are used for heat sinking. Make sure that all ground
pins are soldered onto a suitable large copper ground plane for efficient heat sinking.
Logic input, channel 2. It controls, together with the I12 input, the current level in the output
stage.
Logic input, channel 2. It controls, together with the I02 input, the current level in the output
stage.
Controls the direction of the motor current of MA2 and MB2 outputs. Motor current flows from
MA2 to MB2 when Phase2 is HIGH.
Reference voltage, channel 2. Controls the threshold voltage for the comparator and hence
the output current.
Clock Oscillator, channel 2. Timing pin connect a 56kresistance and a 820pF in parallel
between T and ground.
Logic voltage supply normally +5V.
Clock Oscillator, channel 1. Timing pin connect a 56kresistance and a 820pF in parallel
between T and ground.
Reference voltage, channel 1. Controls the threshold voltage for the comparator and hence
the output current.
Controls the direction of the motor current of MA1 and MB1 outputs. Motor current flows from
MA1 to MB1 when Phase1 is HIGH.
Logic input, channel 1. It controls, together with the I01 input, the current level in the output
stage.
Logic input, channel 1. It controls, together with the I11 input, the current level in the output
stage.
Motor output B, channel 1. Motor current flows from MA1 to MB1 when Phase1 is high.
Comparator input, channel 1. This input senses the instantaneous voltage across the sensing
resistor, filtered through a RC network.
Common emitter, channel 1. Connect the Sense resistor between this pin and ground.
Motor supply voltage, 4 to 40V.
