CMOS circuit for Analog Quartz Watches  
Description  
Features  
The H1137 is a low power 32kHz analog watch chip de-  
signed to drive a stepping motor. Motor pulse width is  
programmable from 0.9765 to 14.65 milliseconds in steps  
of 0.9765 milliseconds. Motor pulse period is program-  
mable from 2 x 1 to 2 x 60 seconds in steps of 1 second.  
Motor pulse period is also programmable from 2 x 0.25 to  
2 x 15.75 seconds in steps of 0.25 seconds. Input and  
output capacitors are integrated on the chip. Their values  
are metal mask selectable. The selection of width, period  
and capacitance are metal options and do not require  
additional bonds.
