TB6598FNG Datasheet Dual Full-bridge Driver

Manufacturer: Toshiba

Overview: 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).

This datasheet includes multiple variants, all published together in a single manufacturer document.

Key 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.
