LB11851M Description
ENA0673A Monolithic Digital IC LB11851M Overview .. Microprocessor Fan Motor Interface Driver The LB11851M 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 ponents.
LB11851M Key Features
- Fan motor interface driver function (FGIN) ⇒ This IC accepts a signal from a microcontroller and interfaces to external
- Variable speed input pin (PWMIN) ⇒ PMOS side PWM control NMOS side current regeneration using slow decay is used to achi
- Built-in kickback absorption circuit (OUT1P/2P) ⇒ This circuit absorbs the kickback current that is generated at phase s
- Built-in current limiter circuit (SENSE) ⇒ This circuit implements a chopper-type current limiting control that operates
- Built-in microcontroller power supply (5VREG)
