MCHPEMC2101-ACZL-TR
Overview
The EMC2101-ACZL-TR is a specialized fan controller and temperature monitor that provides precise thermal management for electronic systems via an SMBus 2.0 interface. It features an integrated internal temperature sensor and supports an external diode-connected transistor for remote sensing, including advanced Beta Compensation and Resistance Error Correction to ensure accuracy. The device offers versatile fan control through either a PWM or a linear DAC output, making it compatible with various cooling configurations.
Why Choose This Part
The EMC2101 stands out for its flexibility, offering both PWM and DAC fan drivers in a single 8-MSOP package. Engineering benefits include Resistance Error Correction, which compensates for series resistance in PCB traces to remote sensors, and Beta Compensation to handle varying transistor geometries accurately.
Applications
Key Specifications
Getting Started
To evaluate this part, interface it with a microcontroller using the 2-wire SMBus pins and provide a 3.3V supply. Microchip offers the ADM00605 evaluation board for testing the EMC2101's features, and software development is simplified by its SMBus 2.0 compliance which includes a TIMEOUT feature to prevent bus lockups.
