22 / 43 page  PMBus 6-Channel Power-Supply Manager 22 Temperature Sensor Operation The device can monitor up to eight different temperature sensors, seven external sensors plus its own internal temperature sensor. The external temperature sensors are all connected in parallel to the master I2C port (MSDA and MSCL pins). The device can support up to four DS75LV devices plus one MAX6695 device. Each of the enabled temperature sensors is measured once a second. The internal temperature sensor is averaged four times to reduce the affect of noise. Each time the device attempts to read a temperature sensor it checks for faults. For the remote diode, a fault is defined as either an open or short across the diode. For the internal temperature sensor, a fault is defined as reading greater than +130NC or less than -60NC. For the I2C temperature sensors, a fault is defined as a communication access failure. Temperature sensor faults are reported by set- ting the temperature reading to 7FFFh. A temperature sensor fault results in the setting of the TEMPERATURE bit in STATUS_BYTE and STATUS_WORD and ALERT is asserted (if enabled in MFR_MODE). No bits are set in STATUS_MFR_SPECIFIC. Reading disabled tempera- ture sensors returns a fixed value of 0000h. The device can control up to four DS75LV digital temper- ature sensors. The A0, A1, and A2 pins on the DS75LV should be configured as shown in Table 6. The thermo- stat function on the DS75LV is not used and thus the O.S. output should be left open circuit. The device can control one MAX6695, which consists of one local temperature sensor and two remote diode tem- perature sensors. Each of the temperature sensors can be reinitialized by disabling and re-enabling the sensor through MFR_TEMP_SENSOR_CONFIG. The valid range for the MAX6695 temperature sensor is -40°C to +125°C. The page assignment is shown in Table 6. The ALERT, OT1, and OT2 pins on the MAX6695 are not used and should be left open circuit. Table 6.
