3.7.3. Undervoltage Lockout (UVLO)
The UVLO circuit unconditionally drives VO low when VDD is below the lockout threshold. Referring to Figures 36
through 39, upon power up, the Si823x is maintained in UVLO until VDD rises above VDD
the Si823x enters UVLO when VDD falls below the UVLO threshold plus hysteresis (i.e., VDD < VDD
