Yamane,
Yes, you can set the bq24151A charge voltage to your customer's desired value but the charge current maximum is 1.25A. I recommend looking at
bq25606 - standalone (no I2C) - use the VSET pin to set the battery voltage
bq25601 - I2C
Hello Rejeesh,
Rejeesh Raj said: is it possible to achieve battery charging current higher than 2A
The bq25898's default charge current is 2.048A as seen on section 6 of the 898 datasheet. If you require higher charge currents than 2A in standalone…
Hey Daniel,
In regards to 1) The FETs are integrated. This application diagram does not show the internal structure of the part, but rather what external components are needed for a typical use of this part. If you note section 8.2 Functiion Block…
Tal,
Unfortunately, no. The default VBATREG is fixed at 3.54V. This feature and the watchdog were safety features which were considered necessary back when LiIon batteries were first being used in cell phones. Listed below are some standalone single…
Vijetha,
The BQ24070 is a linear device so the difference between input and output voltage plays a big part in thermal calculations as the device regulates voltage using an LDO. The BQ24070 can operate at 12V input voltage if the thermal calculations…
Hi Jeong,
On the BQ25601 charge is enabled by default. The IC does not detect battery connection, it will always attempts to charge. When no battery is connected IC will regulate the voltage of the BAT pin capacitor as if it is a small battery. Then…
Chandan,
1. Please follow the d/s. The acceptable range for charge current is 300 mA to 3000 mA
2. For RICHG = 1100 Ω, VBAT = 3.1V or 3.8V, TJ = –40°C - 85°C, Fast charge current accuracy is between 0.516A and .715A.

Other Parts Discussed in Thread: TUSB321AI , BQ24600 , BQ25606 , TUSB422 , BQ25890 Dear Jeff Thank you very much for your answer. After your post and more research I figured out, that USB-PD power supplies only do the handshake on the CC lines of the…
Anatoly,
I recommend an external step down converter. If the step down converter is in the 5-6V range, then you can use a linear regulator based charger like BQ24072 or one of its family members. See family members in the datasheet www.ti.com/.../bq24072…
