Updated temperature accuracy information to
match
Updated figure and pin description for clarification
on anti-parallel diodes.
Changed Data Hold Time to 0.
Note following Electrical Specifications table
changed from: “During the power up time, SMBus
communication is permitted, however the THERM
pin must be pulled low.”
To: “The ALERT and THERM pins will not glitch
low upon power up.”
Changed figure to remove 2-port diode and
replace with transistor diode.
Changed figure to remove 2-port diode and
replace with transistor diode.
Updated diode connections text.
Updated diode figure.
Changed default from 01h to 03h to match the
actual value.
Added table for bit decode.
Identified 5V tolerant pins. Added the following
application note below table: “For the 5V tolerant
pins that have a pull-up resistor (SMCLK,
SMDATA, THERM, ALERT), the voltage difference
between VDD and the pull-up voltage must never
exceed 3.6V.”
Updated voltage limits for 5V tolerant pins with
pull-up resistors.
Added the following note below table: “For the 5V
tolerant pins that have a pull-up resistor (SMCLK,
SMDATA, THERM, ALERT), the pull-up voltage
must not exceed 3.6V when the device is
unpowered.”
Added leakage current.
