Ordering number : ENA1271
Bi-CMOS IC
Three-Phase Brushless Motor Predriver for Variable Speed Control http://onsemi.
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 plement of on-chip protection circuits, including current limiter and lock protection circuits.
