Hi expert,
According to the current needs of customers for diagnosis,
For two faults, short-circuit to ground and short-circuit to power supply, the diagnosis period is 2s, and the fault needs to be diagnosed 5 times and then reported to DTC.
Correspondingly, the detection cycle of the chip should be set to read every 400ms to diagnose the fault.
According to our understanding, when the current of 6424 is abnormal, the chip will automatically shut down the corresponding channel and set it to a high-impedance state, and the corresponding status bit should be cleared, and the diagnosis should be reactivated, so that the chip can re-detect the state.
Would you like to confirm that reading diagnostic information (reading) and activating diagnostic (writing) every 400ms will affect the normal operation of the chip?
(e.g. affecting the timing of mute to produce pop sounds, etc.)
Thanks a lot!
Andy
