EMC2303 Datasheet
EMC2303 Datasheet (Microchip Technology)
Microchip Technology
The EMC2301/2/3/5 family is an SMBus compliant fan controller with up to five independently controlled PWM fan drivers. Each fan driver is controlled by a programmable frequency PWM driver and Fan Spe.
* Up To Five Programmable Fan Control Circuits: - 4-wire fan compatible - High-speed PWM (26 kHz) - Low-speed PWM (9.5 Hz-2240 Hz) - Optional detection of aging fans - Fan Spin Up Control and Ramp Rate Control - Alert on Fan Stall - Up to three selectable default fan speeds for the EMC2303/5
* Watch.
