LB11850V - Sanyo Semicon Device

LB11850V Monolithic Digital IC

of Pre-driver Block *1: SGND is connected to the control circuit power supply system. *2: For the signal-side power stabilization capacitor, the capacitance of more than 0.1µF is used. Connect the capacitor between VCC and GND with the thick pattern and along the shortest route. *3:

Features

• Pre-driver for single-phase full-wave drive →PMOS-NMOS is used as an external power TR, enabling high-efficiency and low-power-consumption drive by means of the low-saturation output and single-phase full-wave drive.
• On-chip speed control circuit →The speed control (closed loop control) using a speed feedback signal makes it possible to achieve higher speed accuracy and lower speed fluctuations when supply voltage fluctuates or load fluctuates, compared with an openloop control system. Separately excited upper direct PWM control method is used as the variable-speed control system.
• Extern.
