GENERAL DESCRIPTION

The EMC1212 is a temperature sensor that communicates with a host over a single-wire SMSC 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 SMSC 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.
