General Description
The EMC1001 is a tiny SMBus temperature sensor
with ±1.5°C accuracy and two interrupts. Packaged in
a SOT23-6, the EMC1001 provides an accurate,
low-cost, low-current solution for critical temperature
monitoring in a PC or in embedded applications.
The EMC1001 generates two separate interrupts with
programmable thermal trip points. The THERM output
operates as a thermostat with programmable threshold
and hysteresis. The ALERT output can be configured
as a maskable SMBus alert with programmable win-
dow comparator limits, or as a second THERM output.
An efficient fan control system can be created since
this output may be used to control a fan.
A power-down mode extends battery life in portable
applications.
Each part number may be configured to respond to one
of four separate SMBus addresses.
