Product Overview

The A3959SLPTR-T is a DMOS Full-bridge PWM Motor Driver for pulse-width modulated (PWM) current control of DC motors, the A3959SLP capable of output current 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.
  • Low RDS (ON) outputs (270 milliohms, typical)
  • Mixed, fast and slow current-decay modes
  • Synchronous rectification for low power dissipation
  • Internal UVLO and thermal-shutdown circuitry
  • Crossover-current protection
  • Internal oscillator for digital PWM timing
