Description
Motor output B, channel 1. Motor current flows from M
to M
when Phase
is HIGH.
Common emitter, channel 1. This pin connects to a sensing resistor R
to ground.
Motor output A, channel 1. Motor current flows from M
to M
B1
when Phase
is HIGH.
Motor supply voltage, channel 1, +10 to +40 V. V
and V
should be connected together.
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.
Phase
Controls the direction of motor current at outputs M
A1
and M
B1
. Motor current
flows from M
to M
when Phase
is HIGH.
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
and a 4 700 pF capacitor to ground
to obtain the nominal switching frequency of 23.0 kHz and a digital filter blanking time of 1.0
μ
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.
Phase
Controls the direction of motor current at outputs M
A2
and M
B2
. Motor current
flows from M
to M
when Phase
is HIGH.
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
and V
should be connected together.
Motor output A, channel 2. Motor current flows from M
to M
when Phase
is HIGH.
Common emitter, channel 2. This pin connects to a sensing resistor R
to ground.
Motor output B, channel 2. Motor current flows from M
A2
to M
B2
when Phase
2
is HIGH.
SO pin 1 & 24 is "Not Connected"
