Technical Note
13) Ground wiring patterns
The power supply and ground lines must be as short and thick as possible to reduce line impedance. Fluctuating voltage
on the power ground line may damage the device.
14) STB pin voltage
Set the STB pin voltage to 0.3 V or lower when setting channels to a standby state, or to 2.0 V or higher when setting
channels to an operational state. Do not lengthen transition times or fix the STB pin voltage to values higher than 0.3 V or
lower than 2.0 V. Doing so may cause the IC to malfunction.
15) Common supply voltage
Use a common supply voltage for both the driver block and the main block. The IC is not compatible with applications
requiring the driver block to be used while applying user-selected voltages.
16) Setting the MAX DUTY
MAX DUTY limitations may not operate when using the IC at high frequencies. When using the IC in such applications,
allow for sufficient margins when setting external components.
