DESCRIPTION
The DS1227 Kickstarter is a unique CMOS circuit which combines power conversion and microenergy management functions for battery operated systems. Using its integral DC-DC converter, the DS1227 supplies +5V on demand from either a 3– or 6–volt battery input.

FEATURES
• Provides step-up regulation and microenergy management for battery-operated systems
• Converts +3V to +6V DC input power source to +5V DC out for system power
• “Kickstarts” system power upon detection of external stimuli:
    - Clock/calendar alarm
    - Sensor trip; such as from a photo diode
    - Incoming activity to a serial port
    - Any low-level signal transition
• Shuts down microcontroller power under software control when operation complete
• Provides 3 auxiliary power outputs for independent powering of system functions
• Allows design of “power on demand” systems
• Insures maximum life of main power source
• Ideally suited for DS5000-based systems
• Available in 20-pin DIP or SOIC packages
• Operating temperature range of –40°C to +85°C
