It also supports low voltage rails (1.7 V to 3.6 V), common 2-wire interfaces, and is available in a small, space efficient package (1.60 mm × 1.60 mm) for easy integration into computing systems. Temperature ranges of –55°C to 150°C are supported. 6 Pin Configuration and Functions YFF Package 16-Pin DSBGA Bottom View Pin Functions PIN TYPE DESCRIPTION NAME NO. ADD B4 Digital input Address select. Connect to GND, V+, SDA, or SCL. D1+ A1 Analog inputs Positive connection to remote temperature sensors. A total of 8 remote channels are supported. An unused channel must be connected to D–. D2+ B1 D3+ C1 D4+ D1 D5+ A2 D6+ B2 D7+ C2 D8+ D2 D– A3 Analog input Negative connection to remote temperature sensors. Common for 8 remote channels. GND A4 Ground Supply ground connection SCL D4 Digital input Serial clock line for I2C- or SMBus-Compatible Two-Wire interface. Input; requires a pullup resistor to a voltage between 1.7 V and 3.6 V (not necessarily V+) if driven by an open-drain output. SDA C4 Bidirectional digital input-output Serial data line for I2C- or SMBus-Compatible Two-Wire interface. Open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. THERM B3 Digital output Thermal shutdown or fan-control pin. Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded. THERM2 C3 Digital output Second THERM output. Active low; open-drain; requires a pullup resistor to a voltage between 1.7 V and 3.6 V, not necessarily V+. If this pin is not used it may be left open or grounded. V+ D3 Power supply Positive supply voltage, 1.7 V to 3.6 V; requires 0.1-µF bypass capacitor to ground. |
