Microchip Technology's EMC2112-BP-TR Dual RPM-Based PWM Fan Controller

The EMC2112-BP-TR is an advanced, dual-output fan controller with RPM-based PWM control from Microchip Technology. This device is designed to manage and enhance the efficiency of system cooling mechanisms, making it an ideal choice for a wide range of applications including personal computers, servers, network equipment, and storage systems.

The EMC2112-BP-TR offers a sophisticated solution for thermal management by controlling the speed of up to two fans based on the RPM feedback without the need for an external microcontroller. This RPM-based approach ensures that fans operate at the desired speed, providing optimal cooling while reducing noise and power consumption.

The controller supports both 3-wire and 4-wire fans, granting flexibility in fan selection and system design. Its built-in fan fault detection and automatic fan restart capabilities enhance system reliability by ensuring continuous operation even in the event of a fan failure.

With its SMBus interface, the EMC2112-BP-TR allows for easy communication with the host system. This enables the host to read fan speeds and other system parameters, as well as adjust fan speed settings as required. The device also features a Watchdog Timer that can reset the system in case of a software failure, providing an additional layer of protection.

The EMC2112-BP-TR is offered in a small 10-pin MSOP package, making it suitable for space-constrained applications. Its extended operating temperature range ensures reliable performance in environments with varying thermal conditions.

Overall, the EMC2112-BP-TR from Microchip Technology is a highly integrated and efficient solution for advanced fan speed control, providing enhanced cooling management to ensure system stability and longevity.
