Interrupt or SMBus alert output. Can be configured as a second THERM output. Open-drain; requires ALERT/THERM2 6 Digital output pullup resistor to voltage between 1.7 V and 3.6 V. D– 3 Analog input Negative connection to remote temperature sensor. D+ 2 Analog input Positive connection to remote temperature sensor. GND 5 Ground Supply ground connection. Serial clock line for SMBus. Input; requires pullup resistor to voltage between 1.7 V and 3.6 V if driven SCL 8 Digital input by open-drain output. Bidirectional digital SDA 7 Serial data line for SMBus. Open-drain; requires pullup resistor to voltage between 1.7 V and 3.6 V. input-output Thermal shutdown or fan-control pin. Open-drain; requires pullup resistor to voltage between 1.7 V and THERM 4 Digital output 3.6 V. V+ 1 Power supply Positive supply voltage, 1.7 V to 3.6 V. 6 Specifications 6.1 Absolute Maximum Ratings Over operating free-air temperature range, unless otherwise noted. (1) MIN MAX UNIT Power supply V+ –0.3 3.6 V THERM, ALERT/THERM2, SDA and SCL only –0.3 3.6 V Input voltage D+ only –0.3 (V+) + 0.3 V D– only –0.3 0.3 V Input current 10 mA Operating temperature –55 127 °C Junction temperature (TJmax) 150 °C Tstg Storage temperature –60 150 °C (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not implied. 6.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all pins(1) ±2000 V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification JESD22-C101, all ±750 pins(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
