Pin description Symbol Pin Description VDD 1 Positive supply voltage. DC voltage from 3.0 V to 5.5 V. D+ 2 Diode current source (anode). D − 3 Diode sink current (cathode). T_CRIT 4 T_CRIT alarm is open-drain, active LOW output which requires an external pull-up resistor. It functions as a system interrupt or power shutdown. GND 5 Power supply ground. ALERT6 ALERT alarm is an open-drain, active LOW output which requires an external pull-up resistor. It functions as an interrupt indicating that the temperature of the on-chip or remote diode is above or below programmed overtemperature or undertemperature thresholds. SDATA 7 SMBus/I2C-bus bidirectional data line. This is an open-drain output which requires an external pull-up resistor. SCLK 8 SMBus/I2C-bus clock input which requires an external pull-up resistor. |
