We would like to know, if enabling and disabling the CE pin multiple times will cause any defeats in the IC or if this is good to go with it. Please let me know your suggestions.
Part Number: BQ24072 In our project we using charging IC BQ24072RGTR model, as per our application 15min report interval once we monitoring the Temperature. We facing some Temperature accuracy issues while charging case, so we need to disable CE pin for…
Part Number: BQ24072 Other Parts Discussed in Thread: BQ24040 Hi there,
I am using your BQ24072RGTR battery charger. If i apply 4.73V in the input i get 0.47A on the battery side... with the same battery, if i apply 4.55V i get just 0.15A on the battery…
Part Number: BQ24072 Hi Team, We have been using BQ24072 for almost the last 10 years. We have a temperature monitoring device. In the battery working condition, the temperature accuracy is almost 0.5 deg C, but on charging time we face 5 to 8 deg C. This…
Hi Martin,
At this point we have not been able to determine a specific action which would lead to the charging issue you are seeing on BQ24072. If possible can you help to provide greater detail into how you are testing the device when you state "…
Part Number: BQ24072 Hello Team, We are currently using BQ24072RGTR charging IC in our Temperature Monitoring Device. We have used rechargeable battery in our device and thus it operates in both battery & charging states. When charging the device we…
Part Number: BQ24072 Hello all,
just wanted to clarify my understanding of the BQ24072 and the short circuit circuitry when an input source IS NOT connected.
My understanding is that if Vout drops more than 250mV below Vbat for a period longer than 250us…
Part Number: BQ24072 Dear Ti team,
As descript in the datasheet and in the thread " ">e2e.ti.com/.../bq24072-output-voltage-of-ic-in-presence-and-absence-of-battery" , for the BQ24072 chip without battery connected the output voltage should…
Hey Bill,
I appreciate your continued updates. At the moment from my end, I'm unable to provide any solution to this behavior until the cause is determined.
