Functional Description
2.4.11.1.3 Clamping of DESAT pin
By setting bit SCFG.DSTCEN, the DESAT signal is clamped to VGND2 while the output stage of the device issues
a PWM OFF command and during blanking time periods (incuding safe turn-off sequences). By clearing bit
SCFG.DSTCEN, the DESAT clamping is only activated during blanking time periods (including safe turn-off
sequences).
2.4.11.1.4 Activation of the Pulse Suppressor
The pulse suppressor function associated with the TTOFF function can be activated by setting bit SCFG.PSEN.
When activated, SRTTOF.RTVAL shall be programmed with a minimum value (see Page 110).
2.4.11.1.5 Configuration of the Verification Mode Time Out Duration
The duration of the time out in verification mode is selectable via bit SCFG.TOSEN.
2.4.11.1.6 Configuration of the TTOFF Delays
The TTOFF delays for Regular and Safe Turn-Off sequences can be programmed separately by writing registers
SRTTOF or SSTTOF. The delay for Regular Turn-Off can also be configured using the Timing Calibration
Feature.
Programming 0H as a delay value disables the TTOFF for the concerned Turn-Off Sequence. Hard turn-off are
performed instead. In case the TTOFF function is wished, a minimum value for the delay has to be
programmed (see Page 110 and Page 112).
When safe two level turn-off is used (non zero delay) in normal operating mode (OPM4), the programmed safe
turn-off delay value shall be higher than the programmed regular two level turn off delay.
2.4.11.1.7 Configuration of the TTOFF Plateau Level
The plateau level for safe two level turn off sequences can be programmed with bit fields SRTTOF.GPR and
SSTTOF.GPS. The plateau level value for safe turn-off sequences shall be lower than the one selected for
regular turn-off sequences.
2.4.11.1.8 Configuration of the DESAT Blanking Time
The blanking time for the DESAT protection can be configured by writing bit field SDESAT0.DSATBT and / or
SDESAT1.DSATBT. In case this function is used, a minimum value for the delay has to be programmed (see
Page 108).
Note:
The programmed OCP blanking time shall be smaller than the programmed DESAT blanking time.
