SE95 Datasheet PDF

NXP Semiconductors SE95

The SE95 is a temperature-to-digital converter using an on-chip band gap temperature sensor and Sigma Delta analog-to-digital conversion technique. The device is also a thermal detector providing an overtemperature detection output. The SE95 contains a number of data registers accessed by a controller via the 2-wire serial I2C-bus interface: • Configuration register (Conf) to store the device settings such as sampling rate, device operation mode, OS operation mode, OS polarity, and OS fault queue • Temperature register (Temp) to store the digital Temp reading • Set-point registers (Tos and Thyst) to store programmable overtemperature shutdown and hysteresis limits • Identification register (ID) to store manufacturer numbers The device includes an open-drain output (pin OS) which becomes active when the temperature exceeds...
