description: |
The ADM1293 and ADM1294 are high accuracy integrated digital power monitors
that offer digital current, voltage, and power monitoring using an on-chip,
12-bit analog-to-digital converter (ADC), communicated through a PMBus
compliant I2C interface.
Datasheets:
https://www.analog.com/en/products/adm1294.html
The SQ24905C is also a Hot-swap controller compatibility to the ADM1278,
the PMBUS_MFR_MODEL is MC09C

The BD12780 and BD12780A are hot-swap controllers from ROHM. They are
functionally compatible with the ADM1278. The main difference between
the BD12780A and the BD12780 is amount of configurable I2C addresses.
Datasheets:

https://fscdn.rohm.com/en/products/databook/datasheet/ic/power/power_switch/bd12780amuv-lb-e.pdf
The BD12790 is a ROHM hot-swap controller, functionally similar to the
ADM1272.
