The metal can is also connected to this pin.Serial clock input for 2 wire communications protocol. Weak pullup(300kΩ typ) is present on this pin.Digital input / output open drain NMOS. In SMBus mode (factorydefault) Serial Data I/O. In PWM mode – PWM output. Weak pullup(300kΩ typ) is present on this pin.VDD External supply voltage.Table 2: Pin description MLX90615Notes:For EMC and isothermal conditions reasons, it is highly recommended not to use any electrical connection tothe metal can except by the Vss pin.The SDA pin is an input Schmidt trigger when the thermometer is operated in the 2-wire SMBus interfacemode.3901090615 Page 5 of 30 Data SheetRev 00128/Aug/2008
