Other Parts Discussed in Thread: TPS25730,
Tool/software:
Hello,
For our Sensor node project, we shall use a single-cell 3.6V Li-Ion Battery pack that can reach up to 17500mAh capacity.
The Sensor node shall be charged with USB (USB TypeC PD, we are using TPS25730 USB PD Controller) and, a 12V Solar panel or from 5V out SMPS. (VCC pin is for solar panel, 5V stands for SMPS out)
The schematic is attached,
What topology should I use for that application at BQ25798's VBUS side (VBUS VAC and ACDRV connections?) for our application?
Should I use Back-to-Back FETs?
What shall be the SYS output (Voltage) when the Prog pin is tied to GND with a 3K resistor?
Could you validate the schematic?
Best regards,
Egemen Aksoy
