Part Number: BQ24167 Tool/software: I'm designing a charger using BQ24167. I'd like to only use the IN input, ignoring the USB-input.
Can I do any of the following:
- Leave USB floating and omit the 1μF capacitor; - Omit the 4.7μF capacitor on PMIDU;…
Part Number: BQ24167
We use BQ24167RGE in our new device. To ensure that everything works as expected I created a simple measurement unit based on Adafruit INA219 FeatherWing and connected it to the battery. Every 100 ms this measurement unit samples…
Nick, bq24167 is the only dual input switching charger that TI offers. The I2C version has a bit to disable reverse boost prevention circuit, but then there is the potential to have a reverse boost event. We have simple FET based circuits to place on…
The voltage between the charger's BAT and GND pins is 4.08V. We put a PMOS between Charger IC BAT pin and Battery, the Rds on is 48mohm(typ).
I'm sorry that I would like to provide a battery gauge log file to explain the exact status that we are are…
Other Parts Discussed in Thread: BQ24167 Hi all,
I am facing strange problem with BQ24167. It's battery detection loop is getting un-stabilized. I have attached waveform for SYS voltage. It is constantly moving from 4.3V (no-battery) to 3.85 V. Surprisingly…
Dear all.
Our customer made 25's ES boards. Only one board, even if there are no battery, it will be during charge state.
1) No battery 2) BAT=4.2V and CHG=Low (pull up) 3) No charge detection phase (Charge detection phase works for other 24 boards…
