Diagnostic Table

In general the status follows the input signal in normal operating conditions.

If any error is detected the status is inverted.

time td(fault) will not be latched and not reported at the diagnosis pins.

Note 2) Overload/short-to-supply - events shorter than min. time td(off) will not be latched and not

reported at the diagnosis pins.

Note 3) Off as long as overtemperature occurs, restart after cooling down.

Note 4) Shutdown latch reset by falling input edge

Analog Current Sensing :

The TLE6214L provides an analog current sensing function for both output channels. By SPI configura-

tion the multifunctional pin CO1 can sink a sense current proportional to the load current of one/ both of

acteristics “5.Analog Current Sense Output”. To achieve the specified accuracy for current sensing the

The specified current sense temperature deviation is related to the typical 25°C
