8.3.3.8 Undervoltage Lockout on Low Voltage Supply (VDD_UVLO)

The device monitors the input supply voltage VVDD (in versions A/C) to prevent unpredictable behavior in the event that the supply voltage is too low. When the supply voltage falls down to VVDD_UVLOF, the device channel outputs are disabled. The device resumes normal operation when VDD rises above the VDDUVLOR threshold.
