Pin Functions
| PIN | TYPE | EQUIVALENT CIRCUIT | FUNCTION | |
|---|---|---|---|---|
| NO. | NAME | |||
| 1 | ADDR | CMOS Logic Input (three levels) |
 |
Address Select Input: One of three device addresses is selected by connecting to ground, left floating, or connecting to VDD. |
| 2 | GND | Ground | Ground | |
| 3 | VDD | Power | Supply Voltage | |
| 4 | SMBCLK | CMOS Logic Input |
 |
Serial Clock: SMBus clock signal. Operates up to 400 kHz. Low-pass filtered. |
| 5 | ALERT | Open-Drain Output |
 |
Digital output which goes active whenever the measured temperature exceeds a programmable temperature limit. |
| 6 | SMBDAT | Open-Drain Input/Output |
|
Serial Data: SMBus bi-directional data signal used to transfer serial data synchronous to the SMBCLK. Low-pass filtered. |
