MCHPEMC2302-1-AIZL-TR
Overview
The EMC2302-1-AIZL-TR is a dual-channel PWM fan controller designed for precise thermal management via an SMBus interface. It features an integrated RPM-based control algorithm that maintains constant fan speeds regardless of supply voltage fluctuations or aging fan components.
Why Choose This Part
The device offers exceptional precision with 1% RPM accuracy using its internal clock and 0.5% accuracy with an external source. It reduces firmware overhead by handling fan spin-up and ramp rate control autonomously while consuming only 350uA of current.
Applications
Key Specifications
Getting Started
To begin development, interface the EMC2302 with a microcontroller via the SMBus pins (SCL/SDA) and configure the PWM frequency to match your 4-wire fan specifications. Engineers should utilize the Fan Stall Alert pin for system-level safety interrupts and can evaluate the device using Microchip's fan control evaluation boards.
