Dear team,
1. Could you please tell me our device how to monitor gate voltage? We found that when we disconnected the resistor Rgon between OUTH and Gate, our device will report GM fault.
2. Can our device support 900V bus voltage? The background is that our device can work normally under 500V with inductive load, but when the bus voltage increased to 900V. Our device will report GM fault.
3. When we test one device, nFLT1 pin is puled low. We read the status registers, STATUS3[GM_FAULT] =1 and STATUS2[OR_NFLT1_PRI]=1, no other fault. But we set CFG9[GM_FAULT_P]=0, and readback is also 0. So GM fault won't pull low the nFLT signal. But there is no other fault, we don't know why the nFLT is pulled low.
Thanks & Best Regards,
Sherry
