... AN44070A Usage Notes 1. 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 IC is recommended that junctions are designed below 70 ∼ 80% of Absolute Maximum Rating.) 2. The protection circuit is incorporated for the purpose of securing safety if the IC malfunctions. ...

Page 18

... AN44070A Usage Notes (continued) 11. 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 (Pin16) and VM2 (Pin3) 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) ...

... PWM operation The PWM operation of this IC assumes the control by the input switching of APWM (Pin19) or BPWM (Pin33). When AN44070A is operated PWM by using other terminals, the duty of the output is extremely different from the duty of the input. Please use APWM or BPWM when AN44070A is operated PWM. ...
