Because of the Thanksgiving holiday in the U.S., TI E2E™ design support forum responses may be delayed from November 25 through December 2. Thank you for your patience.
Hello,
Discontinuous conduction mode commonly occurs at light load operation when the inductor current reaches 0 A before the high side FET is turned on. It makes sense it would occur at low charge current. The charge current is sufficiently low to switch…
Part Number: BQ25618 Other Parts Discussed in Thread: BQ25619 , , , BQ25616 , BQ25611D The safety timer for the BQ25618, BQ25618E, BQ25619, BQ25611D, and BQ25616 functions as a protection against prolonged charging caused by abnormal battery charging status…
Part Number: BQ25618E Hello team,
I would like to use the Bq25618e on a custom design. I would like to use ship mode functionality and Qon push button to power off/on my device. I do not see any issue when VIN not present and Vbat present: Host send ship…

Part Number: BQ25618 Other Parts Discussed in Thread: BQ25619 , , , BQ25616 , BQ25611D The JEITA guideline was released on April 20, 2007 to improve the safety of charging Li-ion batteries. The BQ25618, BQ25618E, BQ25619, BQ25611D, and BQ25616 chargers have…
Part Number: BQ25618E Hello TI team,
I have a custom design with the BQ25618E.
When I measure the /QON voltage, I find VQON=2.65V when VBAT=3.75V and power key not pushed.
In the datasheet, it is specified that there is a 200k pull up to VBAT with a…
Part Number: BQ25618E Hello,
I would like to ask you about the I2C voltage of the BQ25618E. In the I2C item of the I electrical characteristics of the data sheet, it is pulled up at 1.8V as a condition. I want to pull up at 3.3V, is that ok?
Best regards…
Part Number: BQ25618E Other Parts Discussed in Thread: BQ25618 Hello,
I would like to ask you about BQ25618E. Looking at the datasheet, the value of ISYS_OCP_Q4 is not listed. Do you have information on this value? Fixed value? Or is it modifiable with a…
Part Number: BQ25618E Hello,
I am an FAE for a distributor that handles TI products. A colleague of mine asked a question in the thread below. And since I took over the case, I will continue to ask questions in this thread. In the thread below, my customer…
Part Number: BQ25618E I am looking for a Li+ charger for a rechargeable coin cell battery which also has Powerpath and high efficiency switching buck converter. BQ25618E appears to be a good choice. However, the datasheet states that the output voltage…
