Part Number: BQ24715 Other Parts Discussed in Thread: BQ25890 , , BQ25720
Tool/software:
As we know BQ25890 support the feature of ICO to prevent an unknown adapter overload， why doesn’t BQ24715 also support ICO？
Further，why doesn’t BQ24715 support…
Hello Herbet,
What is Min SYS voltage?
Herbert Wang said: there isn't system load,The problem occurs in the idle state
You don't see this issue when system load is applied?

一、In Power off status, maximize charging current is 5v/1.9A 关机充电时，新PCB（V1.2）出现大电流（最大5V/1.9A） 二、In Power up status, In Power off Maximize charging current is 5v/2.5A 开机过程中，插上充电器+电池时，新PCB（V1.2）出现大电流…
Part Number: BQ24715 Tool/software: Dear TI Engineer,
Our new Notebook product supports both Type-C and DC round charging ports. When we use a DC round port adapter, there is a probability of abnormal phase voltage output, but when we use the Type-C port…
Part Number: BQ24715 Tool/software: dears,
what is the function of the minimum system voltage setting? my understanding is that it is used to prevent the system voltage to drop to a very low voltage when battery is depleted. but will it limit the battery…
Part Number: BQ24715 Tool/software: Dear TI Engineer,
Our Tablet project uses BQ24715 as the charging IC (charge current is no more than 5A), but due to product structure limitations, the output bypass grounding capacitor cannot be used as 220uF on…
Hello Fabio,
I don't see any obvious issue with the PCB layout. We suggest mulitple copper layers to dissipate heat to reduce the case temperature without these extra layers we don't have any other ways to increase heat dissipation.

Part Number: BQ24715 Hi
The customer design with BQ24715. When only the adapter is plugged in and the power button is not pressed, the output VBAT voltage ripple is very large.
The circuit is shown in the figure. Please help to check it.
Waiting for…
