Part Number: BQ25703AEVM-732 Hi,
I read the users' guide saying that EN-LEARN register allows the battery to discharge while adapter is present. I don't really understand this function. The batteries in this case are currently discharging, so it is not…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: BQ25703A , EV2400 Hi,
I want to charge 2 Lithium 18650 batteries with BQ25703A EVM and EV2400. I can set charge current limit, charge voltage limit and read charge status. I want to see the…
Part Number: BQ25703AEVM-732 Hi,
In learn mode, it allows the batteries to discharge, the adapter is isolated from the system. The battery supports the system through the BATFET. When EN-HIZ is on, it disable the converter, allowing the batteries to discharge…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: EV2400 , BQSTUDIO Hello,
I'm using BQstudio and the EV2400 communication interface board, and I'd like to configure the registers so that by default the charge current limit is set to something…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: BQ25703A Hi,
I want to charge 1 cell 18650 Lithium battery by BQ25703A EVM. I tested the board as well as downloaded the software following the user's guide and datasheet of the chip. I powered…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: EV2400 , BQ25703A Hi
I followed the BQ2570X Evaluation Module User's Guide to set up host and device. I am using EV2400. However, BQ studio showed up 'Device ACK error'. I have checked all the…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: EV2400 , BQSTUDIO , BQ25703A We use BQ25703AEVM-732 to debug. When the input power is set to 10V/3A, we can configure registers normally. When the input power is set to 5V/3A, we can only write…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: BQSTUDIO I have an eval kit and I have connected a 1S cell configuration with an 18650 2600mAhr battery and a 24Ohm high current resistor on the system load terminal to sink discharge current…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: BQ25703A Hi,
I'm testing OTG function on BQ25703A EVM . I basically followed the EVM user guide and my battery is a 4S 16.8V Li-Battery. when I enable EN_OTG, I can see the output I set…
Part Number: BQ25703AEVM-732 Other Parts Discussed in Thread: BQ25703A I tested BQ25703AEVM-732 and TPS65987-90EVM.
When the USB PD 5A charging, input FET(Q1) of the BQ25703AEVM is too hot.
It goes up to 104 degrees Celsius.
Can I use this to charge usb…
