Overview

3958 A3958SLB CP CP2 CP1 PHASE OSC GROUND GROUND LOGIC SUPPLY ENABLE DATA CLOCK STROBE CHARGE PUMP DMOS FULL-BRIDGE PWM MOTOR DRIVER Designed for pulse-width modulated (PWM) current control of dc motors, the A3958SB and A3958SLB are capable of continuous output currents to ±2 A and operating voltages to 50 V.
Internal fixed offtime PWM current-control timing circuitry can be programmed via a serial interface 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.
The ENABLE input can be programmed via the serial port to PWM the bridge in fa...
