The EMC1823T-1E/9R is a Board Mount Temperature Sensor manufactured by Microchip that provides 1.8V, 3-channel temperature sensing with an I2C interface, shutdown and alert features, and a fixed address. It is designed to measure temperature for optimized system performance in a variety of applications, including automotive, commercial, and industrial systems. It is an I2C slave device and operates at up to 400kHz clock frequency for faster transmission. With its precision of ±1°C accuracy over a temperature range of -40°C to +125°C, it eliminates the need for external calibration and can alert over-temperature conditions. Additionally, it features an extended operating voltage range of 1.8V to 3.6V and consumes current in only 100nA in shutdown mode to save power.
