Overview
The LB11851MC 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 LB11851MC 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) ⇒ This IC accepts a signal from a microcontroller and interfaces to external power
transistors (PMOS and NMOS) to pr...
