ZHCSP55A October 2019 – October 2021 DRV10982-Q1
PRODUCTION DATA
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 in the event of a short-circuit condition on the motor phases. This includes phase shorts to GND, phase shorts to phase, or phase shorts to VCC. The DRV10982-Q1 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.
The DRV10982-Q1 device also provides acceleration current-limit and lock-detection current-limit functions to protect the device and motor (see Section 8.4.7 and Section 8.4.8 ).
