Pinout

Note:

The metal pad on the bottom of the WDFN package is not internally connected to a voltage potential. This pad can

be a “no connect” or connected to GND.

State

Type

SCL

Serial Clock: The SCL pin is used to provide a clock to the device and is used

to control the flow of data to and from the device. Command and input data

present on the SDA pin is always latched in on the rising edge of SCL, while

output data on the SDA pin is always clocked out on the falling edge of SCL.

The SCL pin must either be forced high when the serial bus is idle or pulled-high

using an external pull-up resistor.

Input

SDA

Serial Data: The SDA pin is an open-drain bidirectional input/output pin used to

serially transfer data to and from the device.

The SDA pin must be pulled-high using an external pull-up resistor (not to

exceed 8K

 in value) and may be wire-ORed with any number of other

open-drain or open-collector pins from other devices on the same bus.

Output

EVENT

EVENT: The EVENT pin is an open-drain output pin used to indicate when the

temperature goes beyond the user-programmed temperature limits. The EVENT

pin can be operated in one of three different modes; Interrupt, Comparator, or

Critical Alarm Modes. The ALERT pin must be pulled-high using an external

pull-up resistor for proper operation.

Output

GND in any combination, allowing up to eight devices on the same bus.
