EMC1001
1.5°C SMBus Temperature Sensor in Miniature SOT-23
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 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 window 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.
