5.4.3.3
In case of a short circuit between OUT and VS pin, a major part of the load current will flow through the short circuit.
As a result, a lower current compared to the nominal operation will flow through the DMOS of the BTS50015-1TAA,
which can be recognized at the current sense signal.
5.4.3.4
An over load condition is defined by a current flowing out of the DMOS reaching the current over load I
junction temperature reaches the thermal shutdown temperature
In that case, the SENSE signal will be in the range of
This is a device with latch function. The state of the device will remain and the sense signal will remain on
until a reset signal comes from the IN pin. For example, when a thermal shutdown happened, even the over
temperature condition was disappeared, the DMOS can only be reactivated when a reset signal is send to the IN
pin.
