A3959SLP Features

  • ±3 A, 50 V Output Rating
  • 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

A3959SLP Description

    Designed for pulse-width modulated (PWM) current control of dc motors, the A3959SB, A3959SLB, and A3959SLP are capable of output currents to ±3 A and operating voltages to 50 V. 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, undervoltage monitoring of supply and charge pump, and crossover-current protection. Special power-up sequencing is not required.
