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.
