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).
Features
• Motor supply voltage: V_M ≤ 15 V (max)
• Control supply voltage: V_CC = 2.7 V to 6 V
Weight: 0.07 g (typ.)
• Output current: I_out ≤ 0.8 A (max)
• Low ON-resistance: 1.5 Ω (upper side + lower side typ. @ V_M = 5 V)
• Constant-current control (PWM chopper drive)
• Standby (power-saving) mode
• On-chip thermal shutdown circuit (TSD)
• Compact package: SSOP-16

z This product has a MOS structure and is sensitive to electrostatic discharge. When handling the product,
ensure that the environment is protected against electrostatic discharge by using an earth strap, a
conductive mat and an ionizer. Ensure also that the ambient temperature and relative humidity are
maintained at reasonable levels.
z Install the product correctly. Otherwise, breakdown, damage and/or degradation in the product or
equipment may result.
