Custom IC Project
Project Examples
This turn key IC development program was a servo, power management, and flash memory interface IC intended for use in small form factor Portable Hard Disk Drivers. IC Design Services negotiated the semiconductor development contract, designed 100% of the analog and power management circuits and embedded a 10K gate digital ASIC coded by the Customer. The design contained  IP elements;
  • 3 phase brushless motor driver
        Back EMF Detection, Comutation Controller
  • Class AB & D Voice coil motor driver H Bridge
        Current and Velocity Controls
  • 10 Bit, 20 Mhz Analog to Digital Converter
  • 12 Bit Digital to Analog Converters
  • Switched Capacitor DC-DC Converter(3X positive, 1X Negative)
  • I2C Flash Memory Interface
  • 2 Wire Serial Control Interface
  • OTP based EEPROM
  • Other IP blocks; Reference, Opamps, Comparators, Voltage regulation
This IC  had over 200 specifications and was released to production in less than 1 year.  IC Design Services Statistical design methodology enabled the IC to reach defect limited yield is less than 6 months; device was released to production with yield 5% below defect limited yield. The device shipped in high volume(>20 million units) for many years.
