H1137
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.

Test mode
The TEST pad fulfils two functions:
a) For normal operation, the TEST pad is left open. The
circuit outputs a square wave signal of 512Hz which
can be used for tuning the oscillator.
b) If the TEST pad is connected to VP, the period for
the motor pulses changes to either 2 x 31.25 ms or
2 x 62.5 ms (mask options), while the motor pulse
width remains unchanged (fast motor test).

Functional Description
Oscillator
The 32’768Hz clock frequency is generated by a crystal
oscillator. Input and output capacitors are integrated in
the chip. Their values are metal mask selectable.

Test configuration
Motor drive output
The H1137 contains two push-pull output buffers for driv-
ing bipolar stepping motors (see Fig. 3). Between two
pulses, the two p-channel devices are active for motor
damping.
VP
VP
RL
Reset
Reset
Pulling the RESET input to VP resets the frequency di-
viders and disables the motor pulses. Motor pulses in
progress when the RESET function is applied, will be
completed. After releasing the RESET pad from VP, the
next motor pulse appears with a delay of one half motor
cycle on the drive output MOT1 if the last motor pulse
appeared on MOT2 or vice-versa (see Fig. 3). Due to the
debounce circuitry on the RESET input, VP must be ap-
plied for at least 23.4 ms to be accepted as RESET.
