Part Number: TPS2121 I need to use two power inputs now: one is 12 volts, and the other is a battery pack. When fully charged, its voltage is about 14.1 volts; when the power drops and eventually runs out, the voltage is about 11.5 volts.
The problem…

Tool/software:
Hi.
IN1 (5V), IN2 (4.2V BATT), OV1=PR1=OV2=CP2 are used.
The output consumes about 800mA.
When IN1 is removed from the input, the voltage drops as shown in the attachment…

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…
Part Number: TPS2121 Tool/software: Dear experts,
We're currently in the process of designing a new iteration of one of our products. The behaviour should be as follows;
Only if a USB-PD adapter that is supplying 12V (or more than 11V) is connected…
