FAN8742
Features mon
- Built-in thermal shutdown circuit (TSD)
- 8 Independent voltage sources
- Corresponds to 3.3V or 5V DSP
- 4 selectable mute inputs
Description
Suitable for a 3-phase BLDC (Brush-Less Direct Current) spindle motor driver with PWM, the monolithic FAN8741/FAN8742 IC also includes 2-ch motor drivers with PWM for sled motors and 4-ch linear drivers which drive the focus actuator, tracking actuator, tilt actuator, and loading motor in optical media applications. Designed specifically for high-speed/high-density optical media applications, the FAN8741/FAN8742’s power stage is created by D-MOS transistors which have extremely low RDSON. This enables less heat generation and guarantees improved reliability.
