Product Overview

The A3959SLBTR-T is a DMOS full-bridge PWM Motor Driver designed for pulse width modulated (PWM) current control of DC motors, the A3959 is capable of output currents to ±3A and operating voltage to 50V. Internal fixed off-time PWM current control timing circuitry can be adjusted via control inputs to operate in slow, fast and mixed current-decay modes. PHASE and ENABLE input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM-control signals. Internal synchronous rectification control circuitry is provided to reduce power dissipation during PWM operation. Internal circuit protection includes thermal shutdown with hysteresis, under-voltage monitoring of supply and charge pump and crossover-current protection. Special power-up sequencing is not required.
  • Mixed, fast and slow current-decay modes
