Pin Functions
PINI/O(1)DESCRIPTION
NAMEDGK
VDD1PSupply Pin. Bypass to GND with a 0.1-μF capacitor.
DP2I/OPositive connection to remote temperature sensors. Connect DP to DN if no remote diode is used. Place a 470-pF capacitor between DP and DN for noise filtering (if needed).
DN3I/ONegative connection to remote temperature sensor. Connect DP to DN if no remote diode is used. Place a 470-pF capacitor between DP and DN for noise filtering (if needed).
T_CRIT4I/OOpen-drain critical temperature alert pin. A pullup resistor to VDD (or a separate bus) is required. The pullup resistor value is used to configure the default T_CRIT and ALERT high-temperature limits for the Remote and Local channels. See Adjustable Default T_CRIT High-Temperature Limit for more information.
GND5GGround connection
ALERT6I/OOpen-drain temperature alert pin. A pullup resistor to VDD (or a separate bus) is required. The pullup resistor value is used to configure the default T_CRIT and ALERT high-temperature limits for the Remote and Local channels. See Adjustable Default T_CRIT High-Temperature Limit for more information.
SDA7I/OOpen-drain serial data line. Requires a pullup resistor.
SCL8IOpen-drain serial clock

Input line. Note I2C clock stretching is not supported.
