LB11851FA: Microprocessor Fan Motor Interface Driver
The LB11851FA provides an interface between a microcontroller motor control signal and external MOS transistors. This device can implement a microprocessor fan driver with a minimal number of external components. The LB11851FA is optimal for server and personal computer microprocessor fan drive in response to temperature or other external signals when high precision and high air flow are required.
Features- Fan motor interface driver function (FGIN)
- Variable speed input pin (PWMIN)
- Built-in kickback absorption circuit (OUT1P/2P)
- Built-in current limiter circuit (SENSE)
- Built-in microcontroller power supply (5VREG)
