Design a Custom BoardAbout This Component
N-channel H-bridge brushed DC motor driver supporting 4.5-V to 48-V supply with 4.1-A peak output current and 450-mΩ RDS(on). Integrates PWM control, current regulation via external shunt resistor, and protection features including undervoltage lockout, overcurrent detection, and thermal shutdown. Ideal for industrial motor control applications in appliances, printers, and medical equipment.
Package: SOIC-8-1EP (3.9×4.9mm, EP) · 8 pins
Why does this need a breakout?
8-pin SOIC with exposed pad is difficult to hand-solder reliably due to tight 1.27mm pitch and thermal management requirements. A breakout board brings pins to standard 0.1" spacing for breadboard prototyping while providing proper pad routing and thermal dissipation for audio amplifiers and gate drivers.
