LB1821M Datasheet Power Brushless Motor Pre-driver

Manufacturer: SANYO (now Panasonic)

Overview: Ordering number : EN5686 Monolithic Digital IC LB1821M Power Brushless Motor Pre-Driver IC for OA Equipment Overview The LB1821M is a pre-driver IC that supports direct PWM drive and is appropriate for the power brushless motors used in office automation equipment. A motor drive circuit with the desired output capability (voltage and current characteristics) can be constructed by attaching a driver array at the IC output. The LB1821M includes on chip a speed control circuit that allows the motor speed to be varied using an external clock.

Key Features

  • Direct PWM drive output Speed discriminator + PLL speed control circuit FG and integrating amplifiers Forward/reverse switching circuit Braking circuit (short braking) Speed lock detection output Full complement of on-chip protection circuits, including lock protection, current limiter, and thermal shutdown protection circuits. SANYO: QIP44MA Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Maximum supply volta.
