Quartz Controlled Pulse Generator
U2391B
Description
The monolithic integrated bipolar circuit, U2391B, is
designed as a quartz controlled pulse generator. The
tristate input enables the selection of different pulse
period durations. The internal switch-on monitoring
achieves the start up of the IC when the power-on occurs.
The output pulse can supply a drive signal upto 150 mA,
which is short circuit protected.
Features
D Standard quartz fosc = 32.768 kHz
D Minimum operating voltage 4.5 V/1.5 mA
D Pulse width, tp = 31.25 ms
D Power stage with current limitation:
typical 150 mA
D Tristate period selection: 1/36/60 s
yD Reset and disable possibility
D Operation with C 33 pF, as operational time
counter possible
D Minimum dimensions due to SO-case
Application
Operational time counter
Case: SO8
