Does writing the Reset bit in Register #2 cause the charger to enter Standalone mode or does this just reset the registers to default values and then stay in Host mode?

Other Parts Discussed in Thread: BQ24251 Greetings. We are using a bq24251 (in i2c mode) in a device that is in production. Due to an unrelated issue, a small percentage of these devices are discharging too quickly. The permanently connected 18650s we…
When transitioning from Standalone to Host mode, will the USB_DET bits (Register #3 bits 1 and 0) contain the automatically detected status if read, or should I first perform a manual detection with the DPDM_EN bit (Register #5 bit 4) before reading them…
Hi Wenjia,
I have question about D+/D-detection for SDP with good battery.
By referring Fig.19 in datasheet, bq24251 goes to Hi-Z mode at SDP detected and battery is good. Then does it go to Hi-Z mode after forced D+/D- detection by DPDM_EN bit?
Our customer…
