Part Number: BQ25628 Table 8.5 lists the "ADC Measurement accuracy and performance" and it goes up to 12bit.
E.g. VBAT_ADC has a range of 0..5.572V and an LSB defined as 1.99mV. Does this really mean that the voltage can be measured to an accuracy…
Part Number: BQ25628 We selected the BQ25628 to design into a new consumer product. However, after reviewing the datasheet (and other forum posts) it looks like this chip and many others in TI's portfolio have very low undervoltage cutoff values (e.g.…
Part Number: BQ25628 The recommended values for C_BAT, C_VBUS, C_PMID and C_SYS are given on page 7 of the device datasheet with the comment "(without de-rating)". Are the values to be understood as "before de-rating" or "after de-rating"?…
Part Number: BQ25628
1) When Adapter is present, does the charging voltage appear at the SYS terminal during charging and does the adapter voltage output to the SYS terminal when not charging? 2) Events that cause a reduction in charging current also cause…
Part Number: BQ25628 1) If PMID is not used, should the PMID and PMID_GD pins be OPEN? 2) The description of tPOORSRC_RESTART says after latch-off. Does this mean that it will not return for 15 minutes and will check again after 15 minutes? (Does it return…
Part Number: BQ25628 Other Parts Discussed in Thread: BQ25892
I have a question about the implementation of the BQ25628. When I use the circuit as stated in the datasheet, it causes short power drops which resets the whole system. This is also not only…
