Part Number: BQ21080 Tool/software: We are using a 0.5W 5V solar panel connected to the BQ21080 to charge a LiFePO4 battery. We have programmed a 2.8V Battery Undervoltage LockOut, enabled VinDPM as pseudo MPPT, and 100mA charge current.
In some situations…
Part Number: BQ21080 Other Parts Discussed in Thread: BQ25180 , Tool/software: Hello,
Our customer has a question about lowest input current IIN and the condition. When he looked at the datasheet, the lowest IIN consiton is defined in Sleep mode turning…
Part Number: BQ21080 Hello i am having issues with the BQ21080 and getting it to charge properly no matter what i set the charge current to I get a thermal flag TS_FAULT. My stat and flag registers go to bq21080: STAT: 21: a:80 when i do a short press…
Part Number: BQ21080 Other Parts Discussed in Thread: BQ25180 Tool/software: Hi, TI engineer.
right now I use the part BQ21080.
The charging current is set to 700mA, but at +55°C, the measured current is 550mA.
During charging, the…
Hi Jimmy
Without the SYS capacitor the device may have some stability difficulties. Although it may still charge the device hasn't been characterized without this capacitor so we can't guarantee the device behavior.

Part Number: BQ21080 Dear TI Engineer,
We encountered an issue when using BQ21080. When the input VBUS (IN) suddenly surges, the VBUS (IN) will be short circuited to ground by the front-end OVP device, which causing the voltage of the output SYS and…
Part Number: BQ21080 Dear Community,
I'm using a BQ21080and i have some difficulty with Wake up and Sleep mode .

When the device…
Part Number: BQ21080 Hi,
Question: Is it possible to continue supplying power from the SYS terminal without any "instantaneous interruption" in the system circuit when the VBUS connected to the IN terminal is removed from the following connection state…
