(4) SCP function
Description of operation
When any one of FB1 to FB4 goes High due to the load being shorted or other reason, charging to the SCP pin starts.
If output does not recover during the set time Tscp and the SCP pin voltage exceeds the threshold voltage, the
protection circuit (SCP) operates, and all channel outputs are turned OFF. The SCP_OUT pin set from High to Low.
All outputs are latched OFF by the protection circuit (SCP). This latched state (output OFF) is canceled by setting
the CTL pin Low or by turning the power supply 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.
SCP_OUT
The SCP_OUT pin functions to notify an external microcontroller or other component of the output status (Low
when SCP operates). 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.
