A3959 Features

* ▪ ±3 A, 50 V Output Rating ▪ Low rDS(on) Outputs (270 mΩ, 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 PACKAGES: Pa

A3959 General Description

Designed for pulse width modulated (PWM) current control of DC motors, the A3959 is 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 mod.
