 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.

 20
 21  The SQ24905C is also a Hot-swap controller compatibility to the ADM1278,
 22  the PMBUS_MFR_MODEL is MC09C
