line impedance is high.
5. Hysteresis voltage UP method
When increasing hysteresis voltage for stable system
operation, determine RH as follows and connect
externally.
However, I
CCH
is -5000PPM/°C, so perform
temperature compensation at RH when using over a
wide temperature range.
Hysteresis voltage UP amount ( Vsup) is
Vsup . . RH I

Total hysteresis voltage ( Vstotal) is
Vstotal . . Vs + Vsup

Note: Connect a capacitor between IC pins 1 and 2 if
V
