Part Number: TPS2121
Tool/software:
Hi.
In the example circuit in the DATASHEET, PR1, OV1,OV2, and CP2 are input through the voltage divider circuit.
Table 9-3 shows that (PR1, OV1,OV2, CP2)= ALL GND(0V) will result in AUTO MODE.
Is it possible…
Part Number: TPS2121 Tool/software: Dear reader,
We've just assembled the prototype and it turns out that there's a mistake in my schematic, as reviewed in the linked question. PoE is the voltage source whenever both USB-C PD and PoE are present at…
