Part Number: BQ24195
Hi
My customer design pad with the NE6101 wireless receiving IC to charge BQ24195 encountered the following problems, please help analyze
The power of the wireless receiving IC is 10W (9V, 1.1A) or 5W (5V, 1.1A), but it will always be dragged down by BQ24195.
1. Under normal circumstances, the input current limit is 1.2A, and the charging current is limited to 1.6A. However, the instantaneous input current is as high as 1.7A when the actual measurement is charged, and the wireless receiving IC is disconnected from the TX terminal due to power overload.
2. The input current limit is 0.5A, and the charging current is limited to 0.5A. However, the actual input current is about 1.5A when the actual measurement is charged, and the input current limit register will become 1.5A by itself.
3. The input current limit is 0.9A, and the charging current is limited to 0.5A. However, the actual input current is as high as 1.5A when the charging is actually measured, and the input current limit register does not change.
4. The input current limit is 0.15A, and the charging current is limited to 0.5A. However, the actual input current is as high as 1.7A when the actual charging is measured, and the input current limit register will become 1.5A by itself.
5. The input current limit is 1.5A, and the charging current is limited to 0.5A. However, the actual input current is as high as 1.7A when the charging is actually measured, and the input current limit register does not change.

In the above case, the input voltage limit is 4.52V, so I hope to help solve the problem of large current during charging. This will delay the wireless charging or the power is not enough to reach 9V, 1.1A output; the result will be continuous charging and Power off
Waiting for your reply
Thanks
