Note: When PDN pin is “L”, it is impossible to write the data to all registers. It is initialized.
Do not write the data to Addr.10H~1FH.
• The setting of the registers of Red character as the above Addr.“06H~09H” is recommended to
Dead-Time (for MOSFET Array SLA5097) on the AKD4730-100W evaluation board.
• When the function of ADTC is evaluated, set up the power supply (Vp) to 48V.
