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 drive).
