Descriptions:

The BU21009MUV-E2 is a compact, low-voltage dual H-bridge motor driver designed for driving small DC motors, stepper motors, or other inductive loads. It integrates two independent H-bridge circuits, allowing bidirectional control of two motors or a single stepper motor. The IC supports PWM control for speed regulation and includes built-in protection features for safe operation.

Features:

• Dual H-bridge configuration for bidirectional motor control.
• Low-voltage operation (2.5V to 16V) suitable for battery-powered applications.
• Low on-resistance for efficient power handling.
• PWM input for speed control.
• Built-in thermal shutdown and overcurrent protection.
• Compact VQFN package for space-constrained designs.
• Compatible with microcontrollers and logic-level signals.
