PRODUCTION DATA
If at any time the supply voltage on the VM pin falls below the undervoltage lockout threshold voltage (VUVLO), all MOSFETs in the H-bridge will be disabled and the nFAULT pin driven low. The charge pump is disabled in this condition. Normal operation will resume when the undervoltage condition is removed and VM rises above the VUVLO threshold.
