Bypass to GND with a 0.1-μF (minimum)
ceramic capacitor.
Logic high sets OUT1 high
Logic high sets OUT2 high
Reference voltage output
Input voltage sets output regulation voltage
Open-drain output driven low if fault condition
present
Connect to motor winding
Connect to motor winding
Connect current sense resistor to GND.
Resistor value sets current limit level.

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) Power dissipation and thermal limits must be observed.
