LB11851M
Key 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 provide high-efficiency low-power single-phase full-wave drive.
- Variable speed input pin (PWMIN) ⇒ PMOS side PWM control NMOS side current regeneration using slow decay is used to achieve quite high-speed control.
- Built-in kickback absorption circuit (OUT1P/2P) ⇒ This circuit absorbs the kickback current that is generated at phase switching or power on/off to achieve smooth current regeneration and protect the external transistors against destruction or degradation.
- Built-in current limiter circuit (SENSE) ⇒ This circuit implements a chopper-type current limiting control that operates at startup and during lock protection mode. The current detection voltage is set to a fixed 0.2V internally.
