I²C-Bus Fm+, 1 Degree C Accuracy, Digital Temperature Sensor and Thermal Watchdog


General Features

  • Pin-for-pin replacement for LM75 series but allows up to 27 devices on the bus
  • Power supply range from 2.7 V to 5.5 V
  • Temperatures range from -55 °C to +125 °C
  • Frequency range 20 kHz to 1 MHz with SMBus time-out to prevent hanging up the bus
  • 1 MHz Fast-mode Plus 30 mA SDA drive allows more devices on the same bus but is backward compatible to Fast-mode and Standard-mode
  • 11-bit ADC that offers a temperature resolution of 0.125 °C
  • Temperature accuracy of:
    • ±1 °C (max.) from -25 °C to +100 °C
    • ±2 °C (max.) from -55 °C to +125 °C
  • Programmable temperature threshold and hysteresis set points during operation
  • Supply current of <1.0 μA in shut-down mode for power conservation
  • Stand-alone operation as thermostat at power-up
  • ESD protection exceeds 2000 V HBM per JESD22-A114 and 1000 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
  • Small 8-pin package types: SO8, TSSOP8 and 2 mm x 3 mm HWSON8
  • Small 6-pin package type: TSOP6
