LB1924

Ordering number : ENN5687B Monolithic Digital IC LB1924 Power Brushless Motor Driver IC for Office Automation Equipment Overview The LB1924 is a direct PWM drive output driver IC appropriate for the power brushless motors used in office automation equipment. It includes a speed control circuit, an FG amplifier, and other peripheral circuits and allows a drive circuit to be implemented with a single IC. It allows the number of external components to be reduced by including a lock protection circuit, a kickback absorption diode for the lower output side, and other components on chip.
