本文引用地址:http://butianyuan.cn/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
