ZHCSDA7G July 2014 – February 2018 DRV10983
The overcurrent protection function acts to protect the device if the current, as measured from the FETs, exceeds the IOC-limit threshold. It protects the device from phase-to-phase short-circuit conditions; the DRV10983 places the output drivers into a high-impedance state and maintains this condition until the overcurrent is no longer present. The OverCurr status bit (address 0x10 bit 5) is set.
The DRV10983 also provides acceleration current limit and lock detection current limit functions to protect the device and motor (see Current Limit and Lock Detect and Fault Handling).
