EMC4002 SMBus Fan Driver with Temperature Monitoring
PRODUCT FEATURES
Description
The EMC4002 is a combination fan controller device, temperature sensor, and thermal monitor. It contains two RPM based Fan Control Algorithms that monitor the fan’s speed and automatically adjust the drive to maintain the desired fan speed. These RPM based Fan Control Algorithms act independently and can be coupled to either a Dual Voltage High Side Fan driver or a PWM output. The Dual Voltage High Side fan drivers offer power savings by only drawing current from the necessary supply line based on the output voltage settings.
In addition, the EMC4002 monitors up to nine (9) external diode or thermistor channels and up to seven (7) voltage channels.
