Description:

Dual Dmos Full-bridge Microstepping PWM Motor Driver

Features

* s ±1.5 A, 50 V Continuous Output Rating s Low rDS(on) DMOS Output Drivers s Programmable Slow, Fast, and Mixed Current-Decay Modes s Serial-Interface Controls Chip Functions s Synchronous Rectification for Low Power Dissipation s Internal UVLO and Thermal Shutdown Circuitry s Crossover-Current Prote

Applications

* saving cost and external component count, while minimizing power dissipation. Internal circuit protection includes thermal shutdown with hysteresis, undervoltage monitoring of VDD and the charge pump, and crossover-current protection. Special power-up sequencing is not required. The A3974SED is sup
