SLVSC40H June 2013 – May 2020 DRV8711
PRODUCTION DATA.
If at any time the voltage on the VM pin falls below the undervoltage lockout threshold voltage, all FETs in the H-bridge will be disabled, the UVLO bit in the STATUS register will be set, and the FAULTn pin will be driven low. Operation will resume when VM rises above the UVLO threshold. The UVLO bit will remain set until it is written to 0. The FAULTn pin will be released after operation has resumed.
During any of these fault conditions, the STEP input pin will be ignored.
