Abstract
The present disclosure provides a start-up initialization circuit of motor drive system, including a power amplitude detecting and internal power supply module, a controlled delay module, a waveform shaping module and a power supply judging and adjusting module integrated on a same substrate, configured to detect and manage a voltage change of each node of a drive system in real time to cause a motor drive system to realize a start-up initialization process transit from an off state to a normal working state. The present disclosure finally forms the start-up initialization circuit of motor drive system by integrating the power amplitude detecting and internal power supply module, the controlled delay module, the waveform shaping module and the power supply judging and adjusting module and integrating on a single chip, which greatly ensures the reliability of power on and start-up of the motor drive system.
