Table 4. Pin Function Descriptions
Pin No. Mnemonic Description
1 SCLK Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7311.
2 DOUT Serial Data Output. Data is clocked out on the SCLK falling edge and is valid on the SCLK rising edge.
3 DIN
Serial Data Input. Serial data to be loaded to the parts control registers is provided on this input. Data is clocked
into the registers on the rising edge of SCLK.
4
CS
Chip Select Input. The device is selected when this input is low. The device is disabled when this pin is high.
5 INT
Overtemperature and Undertemperature Indicator. Logic output. The power-up default setting is as an active
low comparator interrupt. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ.
6 CT
Critical Overtemperature Indicator. Logic output. Power-up default polarity is active low. Open-drain
configuration. A pull-up resistor is required, typically 10 kΩ.
7 GND Analog and Digital Ground.
8 V
DD
Positive Supply Voltage (2.7 V to 5.5 V). The supply should be decoupled with a 0.1 μF ceramic capacitor to GND.
