DUAL DMOS FULL-BRIDGE MICROSTEPPING PWM MOTOR DRIVER
Designed for pulse-width modulated (PWM) current control of bipolar microstepping stepper motors, the A3973SB and A3973SLB are capable of continuous output currents to ±1 A and operating voltages to 35 V. Internal fixed off-time PWM current-control timing circuitry can be programmed via a serial interface to operate in slow, fast, and mixed current-decay modes. The A3973SB (DIP) and the A3973SLB (SOIC) are electrically identical and differ only in package style.
FEATURES
■ ±1 A, 35 V Continuous Output Rating
■ Low rDS(on) DMOS Output Drivers
■ Optimized Microstepping via 6-Bit Linear DACs
■ Programmable Mixed, Fast, and Slow Current-Decay Modes
■ 4 MHz Internal Oscillator for Digital Timing
■ Serial-Interface Controls Chip Functions
■ Synchronous Rectification for Low Power Dissipation
■ Internal UVLO and Thermal Shutdown Circuitry
■ Crossover-Current Protection
■ Precision 2 V Reference
■ Inputs Compatible with 3.3 V or 5 V Control Signals
■ Sleep and Idle Modes
