SCL / Vz
this pin for connection of external bipolar transistor to MLX90614Axx to supply the device from external 8…16V source. Digital input / output. In normal mode the measured object temperature is available at this pin Pulse Width Modulated.
SDA / PWM
In SMBus compatible mode the pin is automatically configured as open drain NMOS.
VDD
External supply voltage.
VSS
Ground. The metal can is also connected to this pin. Table 2: Pin description MLX90614 Note: for +12V (+8…+16V) powered operation refer to the Application information section. For EMC and isothermal conditions reasons it is highly recommended not to use any electrical connection to the metal can except by the VSS pin. With the SCL / Vz and PWM / SDA pins operated in 2-wire interface mode, the input Schmidt trigger function is automatically enabled. REVISION 13 - 13 SEPTEMBER 2019 Page 8 of 57 3901090614
