Short-circuit protection is a protective function, also known as fast trip.
The following is an explanation based on the operation example of the TCKE8 series.
Please check each the data sheets for details.
When a large current (exceeding the set current) flows instantaneously through the MOSFET, the eFuse IC determines that the output is short-circuited, and shuts down the MOSFET in a very short time. After shutdown, the MOSFET is automatically turned on by a timer set inside the eFuse IC. At this time, if there is no abnormality in the subsequent ICs or circuits, eFuse IC operates normally. However, if there is a reason for overcurrent to flow, eFuse IC performs overcurrent protective operation.
In the overcurrent protectionthe of auto-retry type, the output current is limited by the overcurrent protection, the output is shut down when the junction temperature rises to the temperature of thermal shutdown, and when the junction temperature drops, the output turns on again to limit the output current.
After that, the recovery cycle is repeated by the following cycles until the overcurrent is eliminated:
“Operation stop → Temperature drop → Overheat protection release → Current clamp → Temperature rise → Overheat protection → Operation stop.”
The overcurrent protection of the latch type shuts down the output when an overcurrent is detected and retains the output off state. Releasing the output-off is performed by once dropping EN/ UVLO signal to the "L" level and then inputting the "H" level signal again.
