Description	Digital Temperature Sensor and Thermal Watchdog
Datasheet	LM75-MaximIntegrated.pdf

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.

SO (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.
