PRODUCTION DATA
DESAT function is used to detect VDS for SiC-MOSFETs or VCE for IGBTs under overcurrent conditions. Figure 7-10 shows the timing diagram of DESAT operation with soft turn-off during the turning on transition.
Figure 7-11 shows the timing diagram of DESAT protection while the power device is already turned on.
