Timing Chart
When the MODE pin is set to the high level and the point of the over current detection is set by using the ILIM pin is
exceeded, the value becomes double the original value.
Also, when the MODE pin is set to the low level, the point of over current detection remains an original value.
Timing chart of the over current detection point switching is as below.
