Allegro A3992SLPTR-T

驱动器 - 全集成，控制和功率级1.5A4.5V ~ 5.5V

Overview

Designed for pulse width modulated(PWM) current control of bipolar microstepped stepper motors, the A3992 is capable of continuous output currents to ±1.5 A and operating voltages to 50 V. Internal fixed off-time PWMcurrent control timingcircuitry can be programmed via the serial interface to operate in slow, fast, or mixed decay modes.

Features and Benefits ▪ ±1.5 A, 50 V continuous output rating ▪ Low RDS(on) DMOS output drivers ▪ Short-to-ground protection ▪ Shorted load protection ▪ Optimized microstepping via six bit linear DACs ▪ Programmable mixed, fast, and slow current decay modes ▪ 4 MHz internal oscillator for digital timing ▪ Serial interface controls chip functions ▪ Synchronous rectification for low power dissipation ▪ Internal UVLO and thermal shutdown circuitry ▪ Crossover-current protection ▪ Inputs compatible with 5 or 3.3 V control signals ▪ Sleep and Idle modes
