LM75 - Digital Temperature Sensor and Thermal Watchdog

General Description

The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector.

The host can query the LM75 through its I2C interface to read temperature at any time.

Key Features

  • ISO (SOP) and μMAX® (μSOP) Packages.
  • I2C Bus Interface.
  • Separate Open-Drain OS Output Operates as Interrupt or Comparator/Thermostat Input.
  • Register Readback Capability.
  • Power-Up Defaults Permit Stand-Alone Operation as a Thermostat.
  • 3.0V to 5.5V Supply Voltage.
  • Low Operating Supply Current 250μA (typ), 1mA (max).
  • 4μA (typ) Shutdown Mode Minimizes Power Consumption.
  • Up to Eight LM75s Can Be Connected to a Single Bus.
  • Pin- and/or Register-Compati.

Digital Temperature Sensor and Thermal Watchdog with 2-Wire Interface LM75 General Description The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtemperature detector. The host can query the LM75 through its I2C interface to read temperature at any time. The open-drain overtemperature output (OS) sinks current when the programmable temperature limit is exceeded. The OS output operates in either of two modes, comparator or interrupt. The host controls the temperature at which the alarm is asserted (TOS) and the hysteresis temperature below which the alarm condition is not valid (THYST).
