PRODUCTION DATA
If the winding current in any coil drops below the open load current threshold (IOL) and the ITRIP level set by the indexer, and if this condition persists for more than the open load detection time (tOL), an open-load condition is detected.
When the ENABLE pin is connected to DVDD, the nFAULT line is released immediately after the open load condition is removed. When the ENABLE pin is Hi-Z, the nFAULT line is released after the open load condition is removed and a nSLEEP reset pulse has been applied. The fault also clears when the device is power cycled or comes out of sleep mode.
