ZHCSH31B August 2017 – February 2018 DRV10987
The overcurrent protection function acts to protect the device if the current, as measured from the FETs, exceeds the IOC-limit threshold. The overcurrent protection function protects the device in the event of a short-circuit condition on the motor phases. A short-circuit condition includes phase shorts to GND, phase shorts to phase, or phase shorts to VCC. The DRV10987 device places the output drivers into a high-impedance state until the lock time tLOCK_OFF has expired. The OverCurr status bit of the FaultReg register (address 0x00, bit 11) is set.
