7.4.2.2.2 High-side Driver Short-circuit Protection

Short-circuit protection monitors each high-side output (OUT5-12) using a 2V comparator on the OUTx node. After the blank time If OUTx voltage does exceed the 2V short-circuit threshold for deglitch time, a short to ground fault is detected and the output is disabled.

The 2V comparator blank time (tSC_BLK) is 40μs for all high side driver outputs. Blank time starts when OUTx is enabled. OUT5 and OUT7 have dedicated deglitch time settings, configurable via bits HS_OUT5_ITRIP_DG, OUT7_ITRIP_DG in the HS_REG_CNFG1 register. OUT6 has dedicated deglitch time settings, configurable via bits HS_OUT6_ITRIP_DG in the HS_REG_CNFG3 register. For OUT8-12 deglitch time settings are shared, configurable via bits HS_OUT_ITRIP_DG in the HS_REG_CNFG3 register. For VPVDD < 20V, all deglitch options (24, 32, 40, and 48μs) are available. For VPVDD > 20V the deglitch time is automatically reduced to 10μs.

Upon short-circuit detection, the corresponding OUTx_OCP fault status bit in the HS_STAT register is latched and the corresponding output is shutoff. The fault bit remains set until the CLR_FLT bit is asserted. The diagram below shows the short circuit behavior for high-side drivers:
