Overview The LB1922 is a single-chip drive circuit that provides the direct PWM drive output appropriate for the power .

and Notes on External Components 1. Speed control circuit Speed control in this IC is implemented with the combination of a speed discriminator circuit and a PLL circuit. The speed discriminator circuit outputs an error output once every two FG perio.
