Part Number: BQ24133 Hello team,
I have a question about the internal circuit of BTST and REGN.
According to the block diagram, BQ24133 has built-in bootstrap diode. However, what is the meaning of the external diode from figure 10-5? How does it affect…
Part Number: BQ24133 Dear Expert
Connect to an external power supply of 15V and start the mainboard. The power consumption of the board is 141mA. Plug in an unfilled battery and use a multimeter to measure the changes in the high (3.3V) and low (0.019V…
Part Number: BQ24133 Hi,
In the below circuit, what happens when battery is disconnected and adapter is plugged in.
Would BQ24133 try to push out constant current into the system?
Part Number: BQ24133 Hi,
At present, the charging status light of BQ24133 keeps flashing after power on, how can I solve this situation? After the battery is put on, it will continue to charge and the red light will be no problem. thanks.

Part Number: BQ24133 Hi,
Going through the datasheet, we came across the below system example.
Can we use the following circuit with 2-cell..?
Also what happens if the cell is removed and the adapter is powered ON in this configuration....?
Hi Jim,
OVPSET should just be a scaled down version of the input. It has 2 internal comparators that have reference voltages equivalent to the UVLO and OVP thresholds specified. The resistor divider is essentially just scaling down the input voltage…
Part Number: BQ24133 Can we configure two li-ion cells of 3.6v having 5000mAh capacity in parallel and charge them.? Is it a common practice ? Is it possible to balance the cells and charge them ?
Input a standalone charger - 5v2.5A.
