System Reset PST573

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.
