One of three motor-supply contacts.
Connect VM1=24, VM2=13 and VM3=14 to the same motor rail.
Operating range 2.5–13.5 V; the 15 V absolute maximum is not a recommended operating voltage.
One of three motor-supply contacts.
Connect VM1=24, VM2=13 and VM3=14 to the same motor rail.
Operating range 2.5–13.5 V; the 15 V absolute maximum is not a recommended operating voltage.
Duty-cycle input for channel B.
Connect to a controller PWM output; use a frequency no higher than 100 kHz.
With opposite direction inputs, PWM LOW selects short brake rather than high-impedance coast.
One of the two direction controls for channel B.
Use defined HIGH/LOW logic together with PWM and STBY; see the control table.
Internal 200 kΩ pulldown. HIGH requires at least 0.7 × VCC.
One of the two direction controls for channel B.
Use defined HIGH/LOW logic together with PWM and STBY; see the control table.
Internal 200 kΩ pulldown. HIGH requires at least 0.7 × VCC.
Reference for control inputs and logic supply.
Join the common ground while keeping motor return currents out of the control path.
LOW places both channels into standby with high-impedance outputs.
Drive HIGH to operate. Keep LOW during initialization.
Internal 200 kΩ pulldown. Standby is not the short-brake mode.
Powers the small-signal control logic.
Use the controller logic rail; the example uses 3.3 V. Add local 100 nF and 10 µF bypass.
Operating range 2.7–5.5 V. Input thresholds track VCC.
One of the two direction controls for channel A.
Use defined HIGH/LOW logic together with PWM and STBY; see the control table.
