User Guide:
The EMC2303 is an SMBus compliant fan controller with up to three independently controlled PWM fan drivers. Each fan driver is controlled by a programmable frequency PWM driver and Fan Speed Control algorithm that operates in either a closed loop fashion or as a directly PWM-controlled device.
The closed loop Fan Speed Control algorithm (FSC) has the capability to detect aging fans and alert the system. It will likewise detect stalled or locked fans and trigger an interrupt.
Additionally, the EMC2303 offers a clock output so that multiple devices may be chained and slaved to the same clock source for optimal performance in large distributed systems.
- 4-wire fan compatible
- High speed PWM (26 kHz)
- Low speed PWM (9.5Hz - 2240 Hz)
- Optional detection of aging fans
- Fan Spin Up Control and Ramp Rate Control
- Alert on Fan Stall
- Up to 3 Selectable Default Fan Speeds
- Watchdog Timer
- 0.5% accuracy from 500 RPM to 16k RPM (external crystal oscillator)
- 1% accuracy from 500 RPM to 16k RPM (internal clock)
- Up to 6 selectable SMBus addresses
- SMBus Alert compatible
- CLK Pin can provide a clock source output
- Available in a 12-pin 4mm x 4mm QFN RoHS Compliant package
