PT2465A - Stepping Motor Driver

Description

The PT2465A is a stepping motor driver, the Hbridges output current controlled by PWM constantcurrent topology.

Built-in micro-step sequencer could generate sinusoidal output current to the stepping motor by a single clock input.

Features

  • Motor power supply voltage range: - Control (VCC): 2.7V to 5.5V - Motor (VM): 2.5V to 16V.
  • Maximum output current: 0.8 A.
  • H-bridge switches on-resistance: Ron = 1.5Ω (high side + low side, VM=7 V).
  • Built-in microstep sequencer ticking by CK clock signal.
  • Programmable phase current excitation modes (2 phase, 1-2 phase, W1-2 phase and 2W1-2 phase).
  • Control input pins with internal pull-down resistors.
  • Motor step monitor output (MO).
  • Thermal shutdown (TSD) p.

DESCRIPTION The PT2465A is a stepping motor driver, the Hbridges output current controlled by PWM constantcurrent topology. Built-in micro-step sequencer could generate sinusoidal output current to the stepping motor by a single clock input. The PT2465A support multiple excitation modes such as 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase mode. The motor rotation revs determinate by the clock frequency applies on CK pin and excitation mode, the CW/CCW pin logic level determinate bipolar stepping motor in forward or reverse direction.
