EM1344中文资料CMOS Circuit for Analog Quartz Clocks with Bipolar Stepping Motor Drive数据手册EM Microelectronic规格书

描述 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 mask-programmable (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.
Solutions:
·Stepper Motor Driver for time-switches
·Analog clocks
