13
  The ADM1293 and ADM1294 are high accuracy integrated digital power monitors

14
  that offer digital current, voltage, and power monitoring using an on-chip,

15
  12-bit analog-to-digital converter (ADC), communicated through a PMBus

16
  compliant I2C interface.

21
  The SQ24905C is also a Hot-swap controller compatibility to the ADM1278,

22
  the PMBUS_MFR_MODEL is MC09C
