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
1
Controls the direction of motor current at outputs M
A1
and M
B1
. Motor current flows from M
A1
to M
when Phase
is HIGH.
Dis
1
Disable input for channel 1. When HIGH, all four output transistors are turned off, which
results in a rapidly decreasing output current to zero.
RC
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.
V
Logic supply voltage, nominally +5 V.
Dis
2
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
2
Controls the direction of motor current at outputs M
A2
and M
B2
. Motor current flows from M
A2
to M
when Phase
is HIGH.
C
2
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.
V
R2
Reference voltage, channel 2. Controls the comparator threshold voltage and hence the
output current.
V
MM2
Motor supply voltage, channel 2, +10 to +40 V.V
and V
should be connected together.
M
A2
Motor output A, channel 2. Motor current flows from M
to M
when Phase
is HIGH.
E
2
Common emitter, channel 2. This pin connects to a sensing resistor R
to ground.
M
B2
Motor output B, channel 2. Motor current flows from M
A2
to M
B2
when Phase
2
is HIGH.
