The primary side is equipped with an UVLO and an OVLO (Over Voltage Lock Out) monitoring an

internally generated supply voltage.

1.3.2. Dead-time generator

The driver has an on-board dead-time generator which overrules the input signals when the dead-

that when the dead-time generator has to intervene, the jitter increases to a maximum of 10ns.

The dead time is by default set at 500ns, but can be changed by modifying R901 and R902. See

chapter 4 for application information.
