LB1976: 3-Phase Brushless Motor Driver
A 3-phase brushless motor driver IC suited for use in direct PWM driving of DC fan motors for air conditioners, water heaters and other similar equipment. Since a shunt regulator circuit is built-in, single power supply operation sharing the same power supply for the motor is supported.
Features- Withstand voltage 60 V, output current 2.5 A
- Direct PWM drive output
- 3 integrated output top-side diodes
- Integrated current limiter
- Integrated FG output circuit
