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 the driver enters into the VDS automatic-retry mode.
The high-side VDS monitors measure the voltage between the VDRAIN and SHx pins and the low side VDS monitors measure the voltage between the SHx and ISEN pins. The VVDS_OCP threshold is programmable from 0.15 V to 1.8 V. Additional information on the VDS monitor levels are described in the Pin Diagrams section.
