TB6598FN

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 io...
