LV8105W
Bi-CMOS IC
For Variable Speed Control
Three-Phase Brushless Motor Predriver
Overview
The LV8105W is a predriver IC designed for variable speed control of 3-phase brushless motors. It can be used to
implement a high- and low-side output n-channel power FET drive circuit using a built-in charge pump circuit.
High-efficiency drive is possible through the use of low noise PWM drive and synchronous rectifying systems.
Functions
• Speed discriminator and PLL speed control system
• Built-in VCO circuit for generating the speed discriminator reference signal
• Speed lock detection output
• Hall bias switch
• Braking circuit (short braking)
• Full complement of on-chip protection circuits, including current limiter and lock protection circuits.
