4 Battery checker (LED ON for low voltage)
Note: Connect a capacitor between IC pins 1 and 2 if
VCC 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, ICCH is
-5000PPM/°C, so perform
temperature compensation at RH when using over a
wide temperature range.
Hysteresis voltage UP amount ( Vsup) is
.
Vsup = RH ICCL
.
Total hysteresis voltage ( Vstotal) is
.
Vstotal = Vs + Vsup
.
Note: Connect a capacitor between IC pins 1 and 2 if
VCC line impedance is high.
