TPS23880: Tps23880: tps23880 writes 12h register and switches manual mode. It cannot be switched. The value of 12h is always 0xff

Part Number: TPS23880
Other Parts Discussed in Thread: TPS23881, ,

We have a project to build a forced supply mode to supply power to non-standard PD. Previously, tps23881 was used, and it was switched to manual mode. After starting the detection, the forced power supply can succeed

In the later stage, due to lack of material, it can only be changed to tps23880, but after changing to 23880, the mode cannot be switched. Write the 12h mode register, and the value of the register has always been 0xff, which can not be written in
