A3901SEJTR-T

The A3901SEJTR-T is a dual full bridge low voltage Motor Driver with full and half-stepping capability. The A3901 driver is designed for low voltage portable applications involving bipolar stepper or brush DC motors. The four inputs (IN1 to IN4) can control a bipolar stepper motor in full or half-step mode and DC motor in forward, reverse or brake mode. The inputs can be PWMed for current or speed control at frequencies up to 250kHz. Internal protection circuitry includes thermal shut down and crossover (shoot-through) protection.

• Sleep mode with zero current drain
• Crossover-current protection
• Thermal shutdown
• Low RDS (ON) outputs
• -20 to 85°C operating temperature range
