TB6598FN fiche technique
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 (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.
