TOSHIBA Bi-CMOS INTEGRATED CIRCUIT SILICON MONOLITHIC DC MOTOR DUAL FULL BRIDGE DRIVER (H-SWITCH) The TB6524FN is a bridge driver most suitable for switching between normal rotation and reverse rotation and can control three modes, normal rotation, reverse rotation, and stop. The driver is capable of handling output current of 100mA. Fixed current operation is also available as the control N <S\\ my) AX method.
