产品概述

The A4980KLPTR-T is an automotive programmable Stepper Driver with crossover-current protection. The A4980 driver is a flexible micro-stepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full, half, quarter and sixteenth-step modes, at up to 28V and ±1.4A. It can be controlled by simple step and direction inputs or through the SPI-compatible serial interface that also can be used to program many of the integrated features and to read diagnostic information. The current in each phase of the motor is controlled through a DMOS full bridge, using synchronous rectification to improve power dissipation.
  • Low RDS (ON) outputs
  • Automatic current decay mode detection/selection
  • Synchronous rectification for low power dissipation
  • Internal OVLO, UVLO and thermal shutdown circuitry
  • Hot and cold thermal warning
  • Stall detect features
