Part Number:DRV10987
Hello,
the explanation about over current protection in drv10983's datasheet as below;
8.3.2.3 Overcurrent Protection (OCP)
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 explanation about over current protection in drv10987's datasheet as below;
8.3.2.3 Overcurrent Protection (OCP)
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.
Q1.Is the behavior difference between DRV10983 and DRV10987??
Q2. If the current exceeds IOC-limit threshold,The devices places the output drivers into a high-impedance state and maintains this condition until the overcurrent is no longer present.
Does it mean that the device return automatically to normal state from a high-impedance state when the current fell down than IOC-limit threshold?
