Other Parts Discussed in Thread: BQ25895
Hello
I have question about IINDPM detection
Which current be detect for IIDPM? is it current at VBUS or current at SW?
According to datasheet IIN_DPM_acc, it seems detect current from SW
I also tested the BQ25895 EVM and set condition as below
To observe IINPDM be trigger when ISYS increase.
VINDPM:4.4V (absolutely)
IINDPM:900mA by input current limit setting
Uncheck ILIM pin
Floating BAT
Just add load in SYS (0~900mA)
I found the IINDPM be trigger at VSYS is 4.19@730mA, VBUS is 5.0V@688mA as below screen capture
My point is why IINDPM be trigger is not at VBUS@900mA
