PRODUCT FEATURES

General Description

Features

Single-wire SMSC BudgetBus™ Sensor Interface

Low Power, 3.0V to 3.6V Supply

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.
