Overview
For Variable Speed Control
Three-Phase Brushless Motor Predriver
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)...
