LM75 (sensor)
|
Added by ALMICO on 20 may 2001

Description: |
The LM75 is a temperature sensor, Delta-Sigma analog-to-digital converter, and digital over-temperature detector with I2C interface. The host can query the LM75 at any time to read temperature. The open-drain Overtemperature Shutdown (O.S.) output becomes active when the temperature exceeds a programmable limit. This pin can operate in either Comparator or Interrupt mode. The host can program both the temperature alarm threshold (TOS) and the temperature at which the alarm condition goes away (THYST). In addition, the host can read back the contents of the LM75's TOS and THYST registers. Three pins (A0, A1, A2) are available for address selection. The sensor powers
up in Comparator mode with default thresholds of 80C TOS and 75C THYST. The LM75's 3.0V to 5.5V supply voltage range, low supply current and I2C interface make it ideal for a wide range of applications. These include thermal management and protection applications in personal computers, electronic test equipment, and office electronics.
