Abstract
In order to enhance the reliability of power operational amplifiers, it is essential to prevent sudden current surges that can lead to an instantaneous increase in circuit temperature and damage the internal transistors of the chip. Through testing its limit current, it was observed that connecting the device to a small load resulted in excessive output current. Therefore, by combining TRIZ theory with ANSYS Q3D simulation software, the resistance of the final protection resistor is approximately 0.13Ω. Aiming at safeguarding the device and significantly improving its life.
