TB6608FNG

TB6608FNG TOSHIBA Bi−CD Integrated Circuit Silicon Monolithic TB6608FNG Stepping Motor Driver IC The TB6608FNG is a PWM constant-current type stepping motor driver IC designed for sinusoidal-input micro-step control of stepping motors. The TB6608FNG can be used in applications that require 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase excitation modes. The TB6608FNG is capable of forward and reverse driving of a 2-phase bipolar stepping motor using only a clock signal. Features Motor power supply voltage: VM = 15 V (max) Control power supply voltage: VCC = 2.7 to 6 V Output current: Iout ≤ 0.8 A (max) Output ON-resistance: Ron = 1.5 Ω (upper and lower sum@VM = 5 V) Decoder that enables microstep control with the clock signal Selectable phase excitation modes (2, 1-2, W1-2 and 2W1-2) Internal pull-down resistors on inputs: 200 kΩ (typ.) Output monitor pin ( MO ) Thermal shutdown (TSD) and undervoltage lockout (UVLO) circuits Small surface-mount package (SSOP20: 0.65 mm lead pitch) Weight: 0.09 g (typ.) This product has a MOS structure and is sensitive to electrostatic discharge. When handling this 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. Do not insert devices in the wrong orientation or incorrectly. Otherwise, it may cause the device breakdown, damage an...
