LB11872H:Three-Phase Brushless Motor Driver
The LB11872H is a three-phase brushless motor driver developed for driving the motors used for the polygonal mirror in laser printers and similar applications. It can implement, with a single IC chip, all the circuits required for polygonal mirror drive, including speed control and driver functions. The LB11872H can implement motor drive within minimal drive noise due to its use of current linear drive.
特性
- Three-phase bipolar current linear drive + midpoint control circuit.
- PLL speed control circuit.
- Speed is controlled by an external clock signal.
- Supports Hall FG operation.
- Built-in output saturation prevention circuit.
- Phase lock detection output (with masking function).
- Includes current limiter, thermal protection, rotor constraint protection, and low-voltage protection circuits on chip
