SE97BTP

SE97BTP Description

The SE97BTP by NXP Semiconductors is a high-precision digital temperature sensor designed for surface-mount applications in demanding environments. Classified as a solid-state thermostat, it features an 11-bit resolution and ±2°C accuracy, ensuring reliable thermal monitoring. Operating within a 3V to 3.6V supply range, it consumes a maximum of 400µA, making it suitable for power-sensitive designs. The sensor communicates via a 2-wire digital interface (I2C/SMBus), enabling seamless integration with microcontrollers and embedded systems. Packaged in an 8-pin HWSON EP with a compact footprint (2mm x 3mm x 0.73mm), it meets EU RoHS compliance and is rated for -40°C to +125°C operation.
