System Reset PST574
Application circuits
1. Normal hard reset
Note: Connect a capacitor between IC pins 1 and 2
if VCC line impedance is high.
2. Battery checker (LED ON for high voltage)
Note: Connect a capacitor between IC pins 1 and 2
if VCC line impedance is high.
3. Battery checker (LED ON for low voltage)
Note: Connect a capacitor between IC pins 1 and 2
if VCC line impedance is high.
4. 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
(Operation will be destabilized if RH is raised too
much.)
Note: Connect a capacitor between IC pins 1 and 2 if
VCC line impedance is high.
