H1137

The H1137 is a low power 32kHz analog watch chip designed 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 programmable from 2 x 1 to 2 x 60 seconds in steps of 1 second. Motor pulse period of H1137 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. H1137's values are metal mask selectable. The selection of width, period and capacitance are metal options and do not require additional bonds.
