PT2465 - Stepping Motor Driver

Description

The PT2465 is a PWM constant-current type stepping motor driver designed for sinusoidal-input micro-step control of stepping motors.

The PT2465 provides several excitation modes for bipolar stepping motor, such as 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase.

Features

  • Range of motor power supply voltage: - Control (VCC): 2.5V to 5.5V - Motor (VM) : 2.5V to 16V.
  • Output current: IOUT ≤ 0.8 A (max).
  • Output ON-resistance: Ron = 1.5Ω (upper and lower total @VM = 7 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) protection.
  • Under voltage lock.

DESCRIPTION The PT2465 is a PWM constant-current type stepping motor driver designed for sinusoidal-input micro-step control of stepping motors. The PT2465 provides several excitation modes for bipolar stepping motor, such as 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase. The PT2465 is capable of forward and reverse driving of a 2phase bipolar stepping motor using only a clock signal.
