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 V_P, 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).

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.

V_P

RL

Reset

Pulling the RESET input to V_Presets 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 V_P, the

next motor pulse appears with a delay of one half motor

cycle on the drive output MOT₁if the last motor pulse

appeared on MOT₂or vice-versa (see Fig. 3). Due to the

debounce circuitry on the RESET input, V_Pmust be ap-

plied for at least 23.4 ms to be accepted as RESET.
