Hi Team,
Here are two questions may need your kindly help.
- Bit[2]
Which DC diagnostic fault refers to in bit [2] in register 0x09, such as S2G, S2P, OL, SL?
Verification step
1: 4 CHs are connected to 4ohm load respectively
2. Initialization data: 0x09=0x00; 0x2b=0x03, 0x04=0x00
3. Pull down the S2G and fault pin of one of them.
Question:
bit [2] has been set to 0, why is it pulled down?
Could you please kindly indicate the meaning of bit [2]?
- MOS
The internal PVDD and outp/n of the IC are output through push-pull, using MOS tube.
If this is the case, there is also a body diode inside the MOS tube, as shown in Figure D6 (marked in red),
It is equivalent to a body diode and an external diode in parallel. Could you please indicate the function of adding this external diode?
