| 摘 要： | 基于IR2132驱动器的TMS320LF2407A测试板驱动电路,由自保护和过电流及欠电压保护组成,并选择长线传输分配脉冲信号.电流在反馈电阻上产生的电压超出设定值时,IR2132启动内部保护电路,关断输出通道,实现电流保护.若负载或驱动电路出现过电流或欠电压,IR2132的FAULT引脚输出制动信号,拉低PDPINT引脚输入电平,关断DSP输出通道并置为高阻态,实现整个控制电路保护.

| Abstract: | The drive circuit of alpha stage TMS320LF2407A is based on the IR2132 driver. It consists of self-protection, over-current and ill-voltage protection. The long-transmission was chosen to assign impulse signals. When the voltage on the feedback resistance over the designed value, the inside protection circuit was operated and the output channels were cut in IR2132 to achieve current protection. If over-current or ill-voltage was appeared in load or drive circuit, the trig signals were outputted by FAULT pin of IR2132; then, the input voltage of PDPINT was lower; the DSP output channels were closed and set as high value; at last, the entire control circuit protection was achieved. |
