本文引用地址：http://dyxdggzs.com/article/178110.htmThe PIP8000FHN is a Power Management Bus (PMBus) protocol compliant, digital power supervisor IC, configurable through a host system to meet dynamic converter performance for a multitude of power supply applications. The PIP8000FHN is able to manage power supply operating conditions as well as to monitor and report the status back to a host system using the PMBus protocol.
The PMBus standard uses the widely accepted Inter-Integrated Circuit (I2C) communication protocol for the hardware interface. A number of additional features are added to enhance the basic I2C communication protocol. These are described in the System Management Bus (SMBus) protocol and include SMAlert.
PIP8000FHN 主要特性：
PMBus serial interface:
Query I/O voltage, I/O current, warnings, faults
Query temperature for up to two temperature sensors
Configure and measure RPM for up to two fans
Sequence start-up and turn-off
Configurable 7-channel A/D with calibration factors
I2C device-address pin stripping
Compatible with most analog controllers
Power-on reset
I2C-bus up to 400 kHz
2.4 V to 3.6 V VDD operating range
