7.3.6 Protection Circuits

The devices are fully protected against supply undervoltage, charge pump undervoltage, output overcurrent, and

device overtemperature events.

7.3.6.1 VM Undervoltage Lockout (UVLO)

If at any time the voltage on the VM pin falls below the UVLO-threshold voltage for the voltage supply, all the

outputs are disabled. Normal operation resumes when the VM undervoltage condition is removed.
