发布时间:2020-06-30 19:21:53 阅读: 来源:机箱厂家

NXP公司的PIP8000FHN是兼容电源管理总线(PMbus)协议的数字电源监视IC,通过主系统进行配置,以满足多模式电源的动态转换器的性能。PIP8000FHN的工作电压为2.4 V 到3.6 V,I/O引脚5V容差。I2C总线的频率高达400kHz。PIP8000FHN可用在DC分布电源系统,网络应用,服务器及其附件,通信设备,工业/ATE电源,存储系统以及AC/DC与DC/DC转换器。本文介绍了PIP8000FHN 主要特性,方框图以及典型应用框图。

本文引用地址: 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

5 V tolerant I/O pins

Thermal sense capabilities

28 pin HVQFN package, 6 mm x 6 mm

PIP8000FHN 应用:

PMBus compliant low voltage, high current density applications

DC power distributed systems

Networking applications

Servers and server accessories

Telecommunication systems

Industrial / ATE power applications

Storage systems

AC/DC and DC-to-DC applications
