3.1. Device Startup
Outputs are held low during powerup until
the outputs follow the states of inputs.
3.2. Under Voltage Lockout
Under Voltage Lockout (UVLO) is provided to prevent erroneous operation during device startup and shutdown or
when
lockout monitors. Each side can enter or exit UVLO independently. For example, Side A unconditionally enters
UVLO when V
