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 drive).
Features
• Motor supply voltage: VM ≤ 15 V (max)
• Control supply voltage: VCC = 2.7 V to 6 V
Weight: 0.07 g (typ.)
• Output current: Iout ≤ 0.8 A (max)
• Low ON-resistance: 1.5 Ω (upper side + lower side typ. @ VM = 5 V)
• Constant-current control (PWM chopper drive)
• Standby (power-saving) mode
• On-chip thermal shutdown circuit (TSD)
• Compact package: SSOP-16
TB6598FNG:
TB6598FNG is a Pb-free product.
The following conditions apply to solderability:
*Solderability
1. Use of Sn-37Pb solder bath
*solder bath temperature = 230°C
*dipping time = 5 seconds
*number of times = once
*use of R-type flux
2. Use of Sn-3.0Ag-0.5Cu solder bath
*solder bath temperature=245°C
*dipping time = 5 seconds
*the number of times = once
*use of R-type flux
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.

The absolute maximum ratings of a semiconductor device are a set of specified parameter values that must not be
exceeded during operation, even for an instant.
If any of these ratings are exceeded during operation, the electrical characteristics of the device may be
irreparably altered, in which case the reliability and lifetime of the device can no longer be guaranteed.
Moreover, any exceeding of the ratings during operation may cause breakdown, damage and/or degradation in
other equipment. Applications using the device should be designed so that no maximum rating will ever be
exceeded under any operating conditions.
Before using, creating and/or producing designs, refer to and comply with the precautions and conditions set forth
in this document.
