产品信息
The EMC1212 is a temperature sensor that communicates with a host over a single-wire Microchip BudgetBus™ Sensor Interface. The EMC1212 monitors one internal diode and one remote temperature zone. Packaged in a SOT23-5, the EMC1212 provides an accurate, low-cost, low-current, solution for critical temperature monitoring in applications such as embedded systems or computers. When used in combination with an Microchip Super I/O host, such as a keyboard controller, a complete thermal management system is created. A power down mode extends battery life in portable applications. The internal 11-bit sigma delta temperature-to-digital converter provides superb linearity, high accuracy and excellent noise immunity.
The EMC1212 is designed to operate with 65nm or 90nm PNP substrate transistor used as a thermal diode with the collector connected to ground.
Note: The EMC1212 is not recommended for new designs. The EMC1412 is the suggested replacement device for this product.
