XC6501A281MR-G

The XC651 series are step-up DC/DC converter and multi voltage detector IC s. CMOS processes and laser trimming technology provide high accuracy and low power consumption.

The XC651 comprises of a PFM controlled step-up DC/DC converter, a voltage detector with 4 x 5 level window comparators built-in, plus 2 other voltage detectors. The step-up DC/DC converter's EN pin provides power consumption savings when the step-up operations are not operating . The series is available in a small TSSOP-16 package.

• Independent power supply for each built-in block:
  • Each of the following built-in blocks is operated by a separate power supply:
  • PFM controlled, step-up DC/DC converter ( PFM DC/DC )
  • 5 level window comparator ( MWVD )
  • Negative Logic: XC651A3 Series
  • Positive Logic: XC651A4 Series
  • Voltage detector 1 with built-in delay circuit ( VD1 )
  • Voltage detector 2 ( VD2 )
• Highly accurate set-up voltage:
  • PFM controlled, step-up DC/DC converter: set-up voltage accuracy ±2.5%
  • 5 level window comparator: set-up voltage accuracy ±2%
  • Voltage detectors 1, 2: set-up voltage accuracy ±2%
