In combination with a typical inductive load, such as a motor, this results in a switched
mode current limitation. That way of limiting the current has the advantage that the power
dissipation in the BTS 7960 is much smaller than by driving the MOSFETs in linear
mode. Therefore it is possible to use the current limitation for a short time without
exceeding the maximum allowed junction temperature (e.g. for limiting the inrush current
during motor start up). However, the regular use of the current limitation is allowed as
long as the specified maximum junction temperature is not exceeded. Exceeding this
temperature can reduce the lifetime of the device.
4.3.5
The device is short circuit protected against
• output short circuit to ground
• output short circuit to supply voltage
• short circuit of load
The short circuit protection is realized by the previously described current limitation in
combination with the over-temperature shut down of the device
