Determine the current flowing into the power switching
circuit (comparator), (3mA to 10mA at V H power
switching)
Ripple filtering resistors
(Used with C05 and C06 to form a ripple filter.)
Input bias resistors
(Virtually determine the input impedance.)
Oscillation prevention resistor
Oscillation prevention resistor
Used with R18 and R19 to determine the voltage gain
VG. (VG should desirably be determined by the R14
and R15 value.)
Used with R14 and R15 to determine the voltage gain
VG.
Input filtering resistor
Output emitter resistors
(Use of cement resistor is desirable)
Use a limiting resistor according to the voltage applied to the standby pin so that it remains within the rating.
Oscillation prevention capacitors.
• Insert the capacitors as close to the IC as possible to
