Typical Application Diagram

Note 1: The power supply capacitor should be connected as close as possible to the IC.

Note 2: When connecting the motor pins through the capacitor for reducing noise, connect a resistor to the capacitor

to limit the charge current.

Note 3: Avoid using common impedance for GND and PGND.

by short-circuiting between outputs, air contamination faults, or faults due to improper grounding, or by

short-circuiting between contiguous pins.
