There is an approximate 20°C (Typ.) thermal hysteresis.
To eliminate motor noise, connect a capacitor between OUT1 and GND and between OUT2 and GND. Alternatively,
connect a capacitor between OUT1 and OUT2, and also a diode between OUT1 and GND and between OUT2 and
GND (see the figure below).
OUT1
Large currents are carried by the motor power supply and motor ground for these ICs. Therefore, the layout of the
pattern of the PC board and the constants of certain parameters for external components, such as the capacitor
between the power supply and ground, may cause this large output current to flow back to the input pins, resulting in
output oscillation or other malfunctions. To prevent this, make sure that the PC board layout and external circuit
constants cause no problems with the characteristics of these ICs.
The power dissipation will fluctuate depending on the mounted conditions of the IC and the ambient environment.
Make sure to carefully check the thermal design of the application where these ICs will be used.
The power consumption by the IC varies widely with the power supply voltage and the output current. Give full
consideration to the power dissipation ratting and the thermal resistance data and transient thermal resistance data,
to provide a thermal design so that none of the ratings for the IC are exceeded.
Make sure that the output current and supply voltage do not exceed the ASO values.
To ensure reliability, it is recommended that the mode switching for the motor pass once through the open mode.
