following current limiters have been tested: |

|
|
|
|
- 0.5A PPTC fuse: it takes too long to trigger (> 1s), and switch off is not reliably detected |
|
|
|
|
- MT9700: it has no over-current signal |
|
|

- SY6288AAAC: the (fixed) current limit is not 0.6A, but around 1.5A |
|

- TJ2242GSF6: over-current is only detected after 3s (instead of specified 100us, probably caused by thermal shutdown), and it is not signaled |
