Description

The H1344 is a low power 32Khz analog clock integrated circuit designed in HCMOS technology to drive a bipolar stepping motor. A set of capacitors is provided on H1344 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
