PRODUCTION DATA.
The gate drivers implement adjustable VDS voltage monitors to detect overcurrent or short-circuit conditions on the external power MOSFETs. When the monitored voltage is greater than the VDS trip point (VVDS_OCP) for longer than the deglitch time (tOCP), an overcurrent condition is detected and action is taken according to the device VDS fault mode.
The high-side VDS monitors measure the voltage between the VDRAIN and SHx pins.The low-side VDS monitor measures between the DLx and SLx pins.
The VVDS_OCP threshold is programmable from 0.06 V to 1.88 V. For additional information on the VDS monitor levels, see the Register Maps section for SPI devices and in the Pin Diagrams section hardware interface device.
