Description
Motor output B, channel 1. Motor current flows from M
Common emitter, channel 1. This pin connects to a sensing resistor R
Motor output A, channel 1. Motor current flows from M
Motor supply voltage, channel 1, +10 to +40 V. V
Ground and negative supply. Note: these pins are used thermally for heat-sinking.
Make sure that all ground pins are soldered onto a suitably large copper ground plane
for efficient heat sinking.
Reference voltage, channel 1. Controls the comparator threshold voltage and hence the output
current.
Comparator input channel 1. This input senses the instantaneous voltage across the sensing
resistor, filtered by the internal digital filter or an optional external RC network.
Controls the direction of motor current at outputs M
M
Disable input for channel 1. When HIGH, all four output transistors are turned off, which results
in a rapidly decreasing output current to zero.
Clock oscillator RC pin. Connect a 12 kohm resistor to V
to obtain the nominal switching frequency of 23.0 kHz and a digital filter blanking time of 1.0 s.
Logic voltage supply, nominally +5 V.
Disable input for channel 2. When HIGH, all four output transistors are turned off, which results
in a rapidly decreasing output current to zero.
Controls the direction of motor current at outputs M
M
Comparator input channel 2. This input senses the instantaneous voltage across the sensing
resistor, filtered by the internal digital filter or an optional external RC network.
Reference voltage, channel 2. Controls the comparator threshold voltage and hence the output
current.
Motor supply voltage, channel 2, +10 to +40 V. V
