General Description
The LM75 temperature sensor includes a delta-sigma analog-to-digital converter, and a digital overtempera ture 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, com parator 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). Also, the LM75’s TOSand THYSTregis ters can be read by the host. The address of the LM75 is set with three pins to allow multiple devices to work
on the same bus. Power-up is in comparator mode, with defaults of TOS= +80°C and THYST= +75°C. The 3.0V to 5.5V supply voltage range, low supply current, and I2C interface make the LM75 ideal for many applications in thermal management and protection.

Features
♦ SO (SOP) and µMAX®(µSOP) Packages
♦ I2C Bus Interface
♦ Separate Open-Drain OS Output Operates as
   Interrupt or Comparator/Thermostat Input
