3. Determine this value using the following formula as a guideline. Vr1 is the VR1 (pin 7) voltage
(See the electrical characteristics table.) and
Vthclk is the potential difference between the
upper and lower Vth. (
Vthclk is about 1.0 V)

4. Determine this value using the following formula as a guideline. Here, Vthsld is the SLD control
circuit internal threshold voltage. (See the electrical characteristics table.)

5. The SLD driver maximum output current Iosldmax is determined by the following formula. Here,
Vsldcl is the current limiter reference voltage. (See the electrical characteristics table.)
