6.10.2 VCP Undervoltage Lockout (CPUV)

If at any time the voltage on the VCP pin falls below the CPUV voltage:

  • All the outputs are disabled (High-Z)

  • nFAULT pin is driven low

  • The charge pump remains active

Normal operation resumes (driver operation and nFAULT released) when the VCP undervoltage condition is removed.
