... AN44060A Usage Notes [Precautions for this IC] Perform thermal design work with consideration of a sufficient margin to keep the power dissipation based on supply voltage, load, and ambient temperature conditions. The protection circuit is incorporated for the purpose of securing safety if the IC malfunctions. Therefore, design the protection circuit so that the protection circuit will not operate under normal operating conditions. The ...

... AN44060A Usage Notes (continued) Set the value of the capacitor between the VPUMP and GND pins so that the voltage on the VPUMP pin (pin 21) will not exceed any case regardless of whether transient phenomenon or not while the motor standing by is started. This IC employs a PWM drive method that switches the high-current output of the output transistor. Therefore, the IC is apt to generate noise that may cause the IC to malfunction or have fatal damage ...

... AN44060A Usage Notes (continued) A high current flows into the IC. Therefore, the common impedance of the PCB pattern cannot be ignored. Take the following points into consideration and design the PCB pattern of the motor. A high current flows into the line between the VM1 (pin 8) and VM2 (pin 22) pins. Therefore, noise is generated with ease at the time of switching due to the inductance (L) of the line, which may result in the malfunctioning or destruction of the IC (see the circuit diagram on the left-hand side) ...
