Design Considerations
1. Method to calculate the set current value for shutter control
The output current can be set from the internal reference voltage and the detection resistors, each connected between
VM and RFD pins and between RFS pin and GND.
IOUT = Internal reference voltage 0.125V ÷ detection resistor
From the above equation, the current value to flow from OUT2 to OUT1 when the detection resistor 1
is connected
between the RFS pin and GND can be determined to be about 125mA.
Similarly, the current value to flow from OUT1 to OUT2 when the detection resistor 1
is connected between VM and
RFD can be determined to be about 125mA.
2. Changeover between the constant current and saturation drive
Saturation drive is made by deleting the detection resistors between VM and RFD pins and between the RFS pin and
GND.
3. OUT4 and OUT8 independent control with INA and INB pins
When the INA or INB pin is set at “H”, OUT4 and OUT8 are activated regardless of the input conditions of MD1 to
MD3 and IN1 to IN2.
4. Photo sensor driving transistor
By setting the SWPI pin to “H”, the photo sensor driving transistor is activated.
When thermal shutdown and VCC low-voltage cut circuits are activated, OUT1 through OUT8 are turned OFF under
control of the internal circuit. But the output (PI) of photo sensor driving transistor continues operation.
