EMC1201/EMC1202
Single/Dual Single-Wire Temp Sensor in SOT23-5 Using SMSC BudgetBus™ Sensor Interface
Note: These products are companions to the KBC1102 or KBC1122 and are intended to be used in conjunction with them.
General Description
The EMC1201 and EMC1202 are temperature sensors that communicate with a host over a single-wire SMSC BudgetBus™ Sensor Interface. The EMC1201 has an
internal temperature sensor and the EMC1202 adds one remote diode. Packaged in a SOT23-5, the EMC1201 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.
