6 / 24 page ADT7420 Preliminary Technical Data Rev. PrA | Page 6 of PIN CONFIGURATION AND FUNCTION DESCRIPTIONS 12 11 10 1 3 4 VDD GND CT 9 INT SCL A0 2 SDA A1 TOP VIEW (Not to Scale) ADT7420 NOTES 1. NC = NO CONNECT. 2. THE EXPOSED PAD IS CONNECTED INTERNALLY. FOR INCREASED RELIABILITY OF THE SOLDER JOINTS AND MAXIMUM THERMAL CAPABILITY IT IS RECOMMENDED THAT THE PAD BE SOLDERED TO THE GROUND PLANE. Figure 3. Pin Configuration Table 4. Pin Function Descriptions Pin No. Mnemonic Description 1 SCL I2C Serial Clock Input. The serial clock is used to clock in and clock out data to and from any register of the ADT7420. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ. 2 SDA I2C Serial Data Input/Output. Serial data to and from the part is provided on this pin. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ. 3 A0 I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or V DD to set an I 2C address. 4 A1 I2C Serial Bus Address Selection Pin. Logic input. Connect to GND or V DD to set an I 2C address. 5 NC No Connect. 6 NC No Connect. 7 NC No Connect. 8 NC No Connect. 9 INT Overtemperature and Undertemperature Indicator. Logic output. Power-up default setting is as an active low comparator interrupt. Open-drain configuration. A pull-up resistor is required, typically 10 kΩ. 10 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. 11 GND Analog and Digital Ground. 12 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 ground. 13 NC No Connect. 14 NC No Connect. 15 NC No Connect. 16 NC No Connect. |
