Overview

EM MICROELECTRONIC - MARIN SA H1344 CMOS Circuit for Analog Quartz Clocks with Bipolar Stepping Motor Drive Description The H1344 is a low power 32kHz analog clock integrated circuit designed in CMOS technology to drive a bipolar stepping motor.
A set of capacitors is provided on chip to be connected, in any combination, to the two oscillator terminals, with a maximum total capacitance of 48pF.
Both the motor pulse period and the motor pulse width are maskprogrammable (see page 6 for already available options).
For versions v143 and v221, the TEST1 and TEST2 pins are only for test and must not be used in the application.
Applications  Stepper Motor Driver for time-switches  Analog clock...
