TB6598FN/FNG TENTATIVE TOSHIBA Bi-CMOS Integrated Circuit Silicon Monolithic TB6598FN/FNG Dual Full-Bridge Driver for Stepping Motors The TB6598FN/FNG is a 2-phase bipolar stepping motor driver employing an LDMOS structure with low ON-resistance for output drive transistors.

By applying four input signals (EN1, EN2, IN1, IN2), it is possible to control the rotation direction (forward/reverse) of 2-phase/1-2-phase stepper motor.

It is also possible to achieve constant-current drive (PWM chopper
