Functional Description
2.4.11.1.9 Configuration of the OCP Blanking Time
The blanking time for the OCP protection can be configured by writing bit field SOCP.OCPBT. Programming 0H
deactivates the blanking time feature which leads to an immediate reaction on OCP. The programmed
blanking time shall not exceed a maximum value (see Page 109).
Note:
The programmed OCP blanking time shall be smaller than the programmed DESAT blanking time.
2.4.11.1.10 Configuration of DACLP Activation Time
The DACLP activation time after hard commutation can be programmed by writing bit field SACLT.AT. In case
value 0H is programmed, the device delivers at DACLP a constant High level. In case an activation time is
required, a minimum value for the delay has to be programmed (see Page 114). In case value FFH is
programmed, the device delivers a constant Low level at DACLP. If the time programmed in SACLT.AT is longer
then the pause to the next pulse on TON the signal will not be canceled, but triggered again that the timer is
starting again.
2.4.11.2 Delay Calibration
In order to compensate for timing errors due to part-to-part variations, a dedicated Timing Calibration
Feature (TCF) has been implemented. The TCF works in such a way that the PWM input signal is used to start
and stop a counter clocked by the Start-Stop Oscillator of the Output Stage. As a result, the following delays
and timing can be configured that way:
• TTOFF delay for Regular Turn-Off.
The TCF allows to compensate for part to part variations of the frequency of the Start-Stop oscillator. This
results in better accuracy for application critical timing. Device specific variations, e.g. temperature related,
are not compensated though.
The TCF can be activated or deactivated in Configuration Mode by writing bit field SSCR.VFS2. The device shall
then be set in OPM6 and the PWM signal applied. Details about the TCF operation are given in Chapter 3.5.9.
