Part Number: BQ25898 Hi!
I have one PCB providing power, and another PCB with the BQ25898 and a battery. In some situations it is important to be able to connect the two PCB's, and have the receiving PCB recognize the connections without actually drawing…
Part Number: BQ25622 Other Parts Discussed in Thread: BQ25898 , , BQ25620 Tool/software: Hi Team,
Can you help to explain why BQ25622 power up time(from REGN raise to ISYS raise) is much longer than BQ25898?
240ms in BQ25622.
40ms in BQ25898

Hi,
We're using BQ25798 IC but facing some issues. We always get "not charging" status, even on default mode (without programming our own configuration to the chip). By…
Part Number: BQ25898 Hi, Could you tell me about PG_STAT and Charging restart condition. If the VBUS voltage drops and PG_STAT becomes 0 and CHRG_STAT becomes 00 (Not Charging), PG_STAT automatically becomes 1 and charging resumes when the VBUS voltage…

Hi, Let me ask you about VBUS_STAT register ? Does VBUS_STAT automatically update to 000 when VBUS is disconnected? Input Source type Detection is described in datasheet 9.2.3.3. However, the conditions under which VBUS_STAT returns…
Part Number: BQ25898 Hi. Could you tell me about CHRG_FAULT? 1. Is CHRG_FAULT bit valid even when CHRG_STAT bit is not charging status? If ”VBUS > VACOV or VBAT < VBUS < VVBUSMIN(typical 3.8V)” is satisfied, does CHRG_FAULT bit become input fault even…
Part Number: BQ25898 Hi. Let's talk about the input current limit setting. I have two questions. 1. IINLIM values of "page 28" and "page 34" in the datasheet are different. Which is the correct value? Page28:3.25A / Page34:3.15A 2. Customer has tested…
Part Number: BQ25898 Hello,
We would like to measure the sleep current consumption of the BQ25898 in our test production.
To get accurate readings we would like to disconnect the battery (BATFET / shipmode) and supply VSYS 3.5V on SYS to power the…
