Local Temperature Sensor IC

Microchip’s line of digital local temperature sensors are single channel digital output temperature sensors for monitoring various heat sources.  These I2C and SPI sensors have typical temperature accuracy performance capability to deliver up to ±0.25°C or ± 0.5°C. They are good for placement next to a heat source or air flow temperature location on circuit board.  Selectable temperature resolutions and conversion rates, multiple critical temperature limits, fault-tolerance queuing, selectable hysteresis thresholds, and non-volatile configuration and temperature registers to retain settings even when devices are powered off. Industry-first solutions that integrate Microchip’s industry-leading non-volatile memory technology to allow customers to not only store critical system temperature data but also application-specific configuration, user preference data, and temperature event data logging.
