1°C Temperature Sensor with Beta Compensation
Datasheet
The EMC1402 will respond to the ARA in the following way:
1. Send Slave Address and verify that full slave address was sent (i.e. the SMBus communication
from the device was not prematurely stopped due to a bus contention event).
2. Set the MASK bit to clear the ALERT pin.
APPLICATION NOTE: The ARA does not clear the Status Register and if the MASK bit is cleared prior to the Status
Register being cleared, the ALERT pin will be reasserted.

SMBus Address
The EMC1402-2 responds to hard-wired SMBus slave address as shown in Table 1.1.
Note: Other addresses are available. Contact SMSC for more information.
SMBus Timeout
The EMC1402 supports SMBus Timeout. If the clock line is held low for longer than 30ms, the device
will reset its SMBus protocol. This function can be disabled by clearing the TIMEOUT bit in the
Consecutive Alert Register (see Section 6.11).
