| 1. general description the pip8000fhn is a power management bus (pmbus) protocol compliant, digital power supervisor ic, con?gurable through a host system to meet dynamic converter performance for a multitude of power supply applications. it is also 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 (i 2 c) communication protocol for the hardware interface. a number of additional features are added to enhance the basic i 2 c communication protocol. these are described in the system management bus (smbus) protocol and include smalert. 2. features n pmbus serial interface: u query i/o voltage, i/o current, warnings, faults u query temperature for up to two temperature sensors u con?gure and measure rpm for up to two fans u sequence start-up and turn-off n con?gurable 7-channel a/d with calibration factors n i 2 c device-address pin stripping n compatible with most analog controllers n power-on reset n i 2 c-bus up to 400 khz n 2.4 v to 3.6 v v dd operating range n 5 v tolerant i/o pins n thermal sense capabilities n 28 pin hvqfn package, 6 mm 6 mm 3. applications n pmbus compliant low voltage, high current density applications n dc power distributed systems n networking applications n servers and server accessories n telecommunication systems n industrial / ate power applications n storage systems pip8000fhn pmbus compliant digital power supervisor rev. 02 6 july 2009 preliminary data sheet

pmbus - two lines consisting of a serial clock and serial data, conforming to smbus v. 2.0, including digital lines called control and one smalert. ? seven channels of 10-bit resolution a/d for measurement of temperatures and i/o volts and current with one channel user de?nable. ? two channels of low frequency 16-bit counters for fan speed measurement. ? pulse width modulation (pwm) output with 10 bits of duty cycle resolution for setting a dc level to adjust analog pwm controllers and hence the power supply output voltage. 7.2 operations pmbus de?nes that a compliant device must start and operate stably without pmbus communications. when a module implementing the pip8000fhn is powered up, the pip8000fhn goes through several levels of con?guration, ?nishing by loading the end user operating parameters from nvram, measuring input voltage, checking the power train for proper operating environment and, when con?gured, enables the output voltage. it may operate without any host interaction. if commanded, it can deliver status information. this will allow the host controller to collect data at the system designer's initiative, including long term data for system reliability purposes. finally, it will issue warnings if operating margins are exceeded or perform selected actions if actual operating fault limits are exceeded. 7.3 product functions ? pmbus compliant, support commands are listed in t ab le 10 ? con?gurable overvoltage/undervoltage, overcurrent, and temperature protection ? con?gurable response to fault events and warnings ? con?gurable sequencing ? wide range output voltage ? con?gurable output voltage ramping ? non-volatile memory for storing con?guration values, device speci?cations, etc. 7.4 host interface the pip8000fhn can run stand-alone or a host controller can be connected using the i 2 c interface. with a host controller the pip8000fhn can be controlled and monitored using the pmbus commands as listed in section 10 . 7.4.1 i 2 c slave address any device that exists on the system management bus (smb) as a slave has a unique address called the slave address. for reference, the following addresses are reserved and must not be used by or assigned to any smbus slave device. pip8000fhn_2 ?

con?gurable settings like v o(max) , and v o . ? warning and fault thresholds for overvoltage, overcurrent, and overtemperature. ? calibration information like coef?cients. during start-up the restore_user_all command is called to store all user parameters into the running con?guration. when settings are changed store_user_all can be used to store the changed settings into the user nvram storage area. restore_default_all and store_default_all can be used to change parameters in the default storage area. the running con?guration needs to be used to swap between user and default storage area. 10.3 pmbus commands t ab le 11 contains a list of the pmbus commands. hex = pmbus command hex value, command name = pmbus command name, # = number of data bytes. r/w/c = read / write / command. some commands are r/w where they are only de?ned as read in the pmbus. the write is supported to enable factory programming. table 11. pmbus commands hex command name # smbus transaction type default value supported range comments on, off, and margin testing 00 page 1 r/w 01 operation [1] 1 r/w 0x80 02 on_off config [1] 1 r/w 0x18 03 clear_faults [1] 0c 04 phase 05 reserved 06 reserved pip8000fhn_2 ?
