LB11867RV-W-AH Description

Short technical summary and product information.

The LB11867RV-W-AH from On Semiconductor is a variable speed, single-phase full-wave pre-driver IC for fan motors. This monolithic digital IC is designed for high-efficiency, low-power consumption drive using external PMOS-NMOS components.

 

Key features include variable speed control via an external PWM input, a chopper-type current limiting circuit for startup and lock conditions, and a reactive current cut circuit for silent operation. It also incorporates a minimum speed setting pin, soft start, lock protection, automatic reset, and thermal shutdown circuits.

 

With a maximum supply voltage of 18V and operating temperature range of -30°C to 95°C, this IC is suitable for applications requiring large airflow and current, such as server fans and consumer appliance motors. It is housed in a 16-SSOP surface mount package.

 

Typical applications include computing and peripherals, industrial systems, servers, and vending machines. The device supports bipolar motor types and operates with a parallel interface.
