Other Parts Discussed in Thread: TPS3802
1. FAULT output of TPA3251 is measured to be at high level of 3.3v, while the RESET of TPS3802 is always at low level, so TPA3251 cannot be started.
2. When the MR of TPS3802 is disconnected from the FAULT of TPA3251, TPS3802 can output normally at the RESET, and TPA3251 can start normally.
3. Test environment: no load, no hot, no short circuit.
