NXP LM75BD,118

LM75BD,118 is a digital temperature sensor and thermal watchdog in a 8 pin SOIC package. It is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma-Delta ADC technique with an overtemperature detection output. LM75B contains a number of data registers: configuration register to store the device settings such as device operation mode, OS operation mode, OS polarity and OS fault queue, temperature register to store the digital temp reading, and set-point registers to store programmable overtemperature shutdown and hysteresis limits, that can be communicated by a controller via the 2-wire I2C-bus interface. The device also includes an open-drain output which becomes active when the temperature exceeds the programmed limits. There are 3 selectable logic address pins so that 8 devices can be connected on the same bus without address conflict. Typical applications include system thermal management, PC, electronics equipment and industrial controllers.
