Product specification
32 kHz watch circuits with adaptive motor
pulse
PCA148x series
APPLICATION INFORMATION
Fig.11 Typical application circuit diagram.
(1) Quartz crystal case should be connected to V
DD
. Stray capacitance and leakage resistance from RESET, M1 or M2 to OSC IN should be less than
0.5 pF or larger than 20 M
.
(2) Motor, probe and stray capacitance from M2 or M1 to V
or V
should be less than C
M
= 80 pF for correct operation of the detection circuit.
Driving the motor at its minimum energy, probe and stray capacitance must be avoided.
