Part Number: BQ24038EVM Other Parts Discussed in Thread: BQ24038 Hello,
I am using BQ24038EVM board to understand charging profiles of various capacity batteries with active system load.
Initially: I have recorded VBAT ~ 4.2V (Set by floating VBSEL…
Hi Michael, I am finished my design. I am checking each IC. I had again a doubt about V input of BQ24038.
I've used the BQ24038 only with AC input, I am not going to use the USB input. How do I have to connect the USB input? floating or gnd througth a…

Other Parts Discussed in Thread: BQ24032A , BQ24030 , BQ24038 I was looking for a battery charger that would handle both a DC charger and a USB charger at the same time. The charger needs to be a power path implementation. I had chosen the BQ24032A as it…
Hello Wang,
A few more pins will be needed to be added to the design, but not many. It
was a rough draft.
Actually I was thinking more of a marriage of the TPS2540(A)/1, bq24030,
TPS2041B & TUSB2036/TUSB8040 all in one.
Strictly speaking…
Yes, the battery can fully charge before the timer expires. The timer is simply a safety feature that will kick in if something is wrong. For example, if the battery is the wrong one or is too old and doesn't charge as fast, etc. the timer will stop charging…
Other Parts Discussed in Thread: BQ24035 , TMP300
I have a few questions/comments on the BQ24035 part that I plan to use. I assume it applies to the entire family.
1) I have mobile computer design where I would like to have a temperature monitoring chip…
The spec on page 24 states:
Note that this LDO is only enabled when either AC or USB inputs are present. If the CE pin is low (chip disabled) and AC or USB is present, the LDO is powered by the battery. This is to ensure low input current when the chip…
