EMC2104-BP-TR Power Management ICs - PMIC by Microchip Technology
| Status: | Active |
|---|---|
| Series: | EMC2104 |
| RoHS: | Compliant |
The EMC2104 is an SMBus compliant fan controller with up to five (4 external and 1 internal) temperature channels. The fan drivers can be operated using two methods each with two modes. The methods include an RPM based Fan Speed Control Algorithm and a direct fan drive setting. The modes include manually programming the desired settings or using the internal programmable temperature look-up table to select the desired setting based on measured temperature.
The temperature monitors offer 1°C accuracy (for external diodes) with sophisticated features to reduce errors introduced by series resistance and beta variation of substrate thermal diode transistors commonly found in processors.
The EMC2104 also includes a hardware programmable temperature limits and dedicated system shutdown output for thermal protection of critical circuitry.
