Part Number: BQ24078 Other Parts Discussed in Thread: BQ24072T Hi Sir,
Would you pls comments if bq24078 can work fine as below battery spec.? thanks.
Capacity:500mAh
Charge Voltage:4.2V
Charge Current: 0.5C 250mAor 0.8C 400mA,(hope full charge time…
Part Number: BQ24078 Other Parts Discussed in Thread: BQ24072T , , BQ24075T , BQ24079T , BQ25155 , BQ21061 Hi Sir,
My customer using battery charging temperature will be 0-45 degree C. How to set Rs and Rp?
It only shows the lowest temperature is 51 degree…
Hi,
The main difference between the BQ24075 and the BQ24075T are as follows:
Electrical Characteristics / Feature
BQ24075
BQ24075T
TS Monitoring Method
Current Based
Voltage Based
Recommended Junction Temperature
-40 C to 125 C
0 C to 125 C …
Hello Jesse,
The main difference is that the BQ24072 has a current based NTC monitoring while the BQ24072T has a voltage based NTC monitoring. This means that you have more flexibility of the charging temperature thresholds on the BQ24072T.
Tandeep,
Based on your device marking, it seems you have the BQ24072T which has a voltage based TS functionality and not the BQ24072 which has a current based TS. That is the reason why the TS function is not functioning as expected. Please take a look…
Part Number: BQ24075T Other Parts Discussed in Thread: BQ24072T Hi all Would you mind if we ask BQ24075T? We would like to understand the function "Reverse Current Protection". We assume that Reverse Current Protection has two protections as f…
Problem solved! I just realized the component I've been using is the BQ24072T and not the BQ24072..... Thus the NTC interface for temperature monitoring was wrong, since the thermistor is directly connected to the TS pin, without a voltage divider. Now…
Hello
It may be difficult to get the accuracy you are looking for with the bq24078.
But the bq24072T / 75T / 79T have a more flexable TS pin configuration and are very similar to the bq23078. I recommend taking a look at the T devices first.
Hello Jeff,
1) This only applies to the BQ24072T not the BQ24079T. In the BQ24079T, VOUT will be regulated to 5.5V if VIN > 5.5V. If VIN < 5.5V, VOUT will be equal to the larger of VIN or VBAT.
2) The VIN-DPM feature is only available in either…
