7.3.7.1 VM Supply Undervoltage Lockout (UVLO)

If at any time the input supply voltage on the VM pin falls below the VUVLO threshold, all of the external MOSFETs are disabled, the charge pump is disabled, and the nFAULT pin is driven low. Normal operation resumes (gate driver operation and the nFAULT pin is released) when the VM undervoltage condition is removed.
