Hi Sreejitha,
Please see my comments below.
The BQ25898 is designed to work with an inductor in the range of 1 uH to 2.2 uH. You will need to select an alternate inductor to the one shown in your schematic.
If you plan to disable ILIM pin it is okay…
Hi Nishie-san,
Please see my comments below.
Yuta Nishie said: Is it correct to understand that the VBUS minimum operation voltage is V(VBUS_OP)=3.9V?
Yes 3.9V is VBUS minimum operating voltage for buck converter to function. I also mention VSleep threshold…
Part Number: BQ25898 Hi,
Each time the USB is inserted/removed, the REG0D Bit [7] FORCE_VINDPM is "0" of default.
1) I always want to use FORCE_VINDPM="1," but could you tell me the appropriate time to set the REG0D Bit [7] FORCE_VINDPM?…
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…
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 down…
Hi Yusuke,
Please see my comments below.
1) Yes CHRG_FAULT will return to 00 when VBUS returns to normal, but the customer will need to read REG0C twice in a row to see current status. Section 9.2.9.2 of the BQ25898 datasheet on page 27 explains how REG0C…
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 recovers…
