Monolithic Digital IC
LB1976
DC Fan Motor Driver
Overview
The LB1976 is a three-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 built-in output top-side diodes
• Built-in current limiter
• Built-in FG output circuit
