EMC2112-BP-TR Power Management ICs - PMIC by Microchip Technology
| Status: | Active |
|---|---|
| Series: | EMC2112 |
| RoHS: | Compliant |
The EMC2112 is an SMBus, closed-loop, RPM-based fan driver with hardware (HW) thermal shutdown and reset controller. The EMC2112 offers a single High Side fan driver capable of sourcing up to 600mA from a 5V supply.
The EMC2112 utilizes Beta Compensation (an implementation of the BJT or transistor model for thermal diodes) and Resistance Error Correction (REC) to accurately monitor up to three (3) external temperature zones. These features allow great accuracy for CPU substrate thermal diodes on multiple process geometries as well as with discrete diode-connected transistors. Both Beta Compensation and REC can be disabled on the EMC2112 to maintain accuracy when monitoring AMD thermal diodes.
The EMC2112 provides a stand-alone HW thermal shutdown block. The HW thermal shutdown logic can be configured for a few common configurations based on the strapping level of the SHDN_SEL pin on the PCB. The HW thermal shutdown point can be set in 1°C increments by using a discrete resistor connected to the TRIP_SET pin.
The EMC2112 also provides 5V supply 'power good' function with a threshold of 4.5V. This function is provided on the RESET# pin.
