(4) External input CLK function (CLK_IN)
Switching operation can be synchronized with external clock input (CLK_IN) by using the CLK_IN pin.
External clock (CLK_IN) frequency and input level
When using external clock (CLK_IN) input, input a frequency equal to the internal oscillation frequency +20% or
more to CLK_IN. In addition, the CLK_IN configuration is shown in the figure “CLK_IN (input) equivalent circuit
(outline)” below.
The 0.8V reference voltage and CLK_IN are compared to determine the edges, so input a signal of 0.8V or more
(VCC voltage or less) as the external clock (CLK_IN).
External/internal clock switching
Set the CTL pin Low before switching between the external clock and the internal clock.
Maximum ON duty
The maximum ON duty (Duty_MAX*) of channel 1 to channel 4 is the 85% (typ.) setting. When using the external
clock (CLK_IN), the maximum ON duty (Duty_MAX*) becomes smaller, so care must be taken for the set output
voltage.

(5) SCP function
Description of operation
When FB1 to FB8 go High due to the load being shorted or other reason, charging to the SCP pin starts, and if output
does not recover during the set time Tscp, the protective circuit (SCP) operates. When the protection circuit (SCP)
operates, all channel outputs are turned OFF. When not using the protection function (SCP), the SCP pin must be
shorted to GND_S with a line that is as short as possible.
When the SCP function operates and SCP_OUT goes High, all outputs are latched OFF. This latched state is
canceled by setting the CTL pin Low or by turning the power supply off.
SCP_OUT
The SCP_OUT pin functions to notify an external microcontroller or other component of the SCP (short circuit
protection) and CTL status. The output configuration is an open drain output, and a pull-up resistor is used. When
not used, leave this pin open.
Switching time
The SCP_OUT switching time is set by the capacitor connected to the SCP pin.
