ADVANCE INFORMATION
The DRV7167A implements drain-to-source voltage, VDS, monitoring based short-circuit proteciton on both FETs. After either FET is turned on through HI/LI=high, the device waits for a time tBLANK, following which the VDSvoltage of the FET is sensed. If the voltage is greater than VDSAT, a short circuit is inferred. Thereafter the FET is turned off to prevent damage. This protection operates on a cycle-by-cycle basis. That is, every HI/LI logic low-to-high cycle turns on the FET. If the VDS exceeds the set threshold, the short circuit protection turns off the FET for the remainder of the HI/LI logic-high duration.
