Hello, everyone.
Check resistance is 0.01 Euro, drive voltage is 24V, MOS transistor CSD18531, drive motor running for a period of time began to report BOCP and UVLO errors, clear the mark bit is the same. We also hope to point out which direction to look for the problem
1. OCP error reporting occurs after running for a period of time. When this error occurs for the first time and is cleared by writing 0, subsequent error reporting is very frequent.
2. Figure 1 is Waveform of BOUT.
Figure 2-bit PCB layout
Figure 3 is the schematic diagram.
THANK YOU
3. When OCP occurs, the error is the error of UVLO and BOCP, and the error of UVLO also occurs when the motor is running normally.
