Introduction

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. For versions v143 and v221, the TEST1 and TEST2 pins are only for test and must not be used in the application.

Features

• 32kHz quartz oscillator
• Integrated capacitors, mask selectable
• Single battery operation
• 0.7μA typical current consumption
• Low resistance outputs for bipolar stepping motor
• Mask options for pad designation, motor period and pulse width, alarm frequency, modulation and duty cycle
• Alarm output function compatible with either NPN or PNP - driver transistors
• Alarm input function
• 1024Hz output on ALIN pad for oscillator frequency verification
• Fast test function
• ESD protected terminals

Applications

• Stepper Motor Driver for time - switches
• Analog clocks
