PRODUCTION DATA.
When the input voltage is below the UVLO threshold, the device holds all gate drive outputs in the low (OFF) state. When the input rises above the UVLO threshold, and the ENABLE pin is above the turn ON threshold, the oscillator begins to operate and the start-up sequence is allowed to begin. The UVLO level is internally fixed at 4.2 V.
