LV8105W

www.DataSheet.co.kr Ordering number : ENA1271 Bi-CMOS IC LV8105W 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) Full complement of on-chip protection circuits, including current limiter and lock protection circuits.
