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 and the UVLO bit will reset when VM rises above the UVLO threshold. The FAULTn pin will be released after operation has resumed.
