Part Number: BQ24179 Hi TI team,
When the resistance of PROG is changed from 6.04 kΩ to 8.2 kΩ, BQ24179 cannot be charged, but when it is changed back to 6.04 kΩ, it can be charged normally. May I ask what causes this?
Hi Switch,
With termination disabled and charge enabled, V(BAT) should regulate near V(VSYS) unless either is hitting OVP. If OVP, then the converter turns off briefly until the OVP condition is removed. If charge is disabled, this will not happen.

Part Number: BQ24179 Hi team,
According to datasheet, the SDRV pin should be connected to ground via 1nF cap,when the ship MOS is not assembled. But in customer's design, they use the ship mos and connect the SDRV to ground via cap. Is there any…
Part Number: BQ24179 I need a power supply chip/circuit that has two inputs, 1 being a USB, 2 being a 1-4 cell LiPO battery. The power supply needs to provide 5V at 3A minimum. When the USB is plugging into the circuit it should charge the battery connected…
Part Number: BQ24179 Hi team,
The customer find that when BQ24179 is going to finish charging almost, they hear the howling. They has disabled the PFM, but they still listen to howling. And they enable the OOA but they still listen to the howling.
So…
