Pin Table
Labeled exposed pad in pinout figure and added
row in pin description table. Recommendation is to
ground the exposed pad.
Added conditions for t_HD:DAT. Data hold time
minimum of 0.3µs is required when receiving from
the master.
Renamed from “SMBus and I2C Compliance.” First
paragraph, added first sentence: “The EMC1412 is
compatible with SMBus and I²C.”
And added last sentence: “For information on
using the EMC1412 in an I²C system, refer to
SMSC AN 14.0 SMSC Dedicated Slave Devices in
I²C Systems.”
Filter MAX changed from “2.5nF” to “2.7nF”.
Set revision ID to 04h.
Updated error on ACK bit settings and reorganized
chapter information and moved ALERT pin
considerations.
Reorganized information for temperature
monitoring and ALERT pin considerations.
Changed default from 01h to 03h to match the
actual value.
Added EMC1412-1-AC3-TR in an 8-pin TDFN
package.
Updated voltage on 5V tolerant pins with pull up
from -0.3 to 3.6 to 0 to 3.6. Added thermal
characteristics for TDFN package.
Added package information for the TDFN.
Added package marking information for the TDFN.
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.”
