UDN6118A** is a **dual full-bridge PWM motor driver** manufactured by **Allegro MicroSystems**.

The UDN6118A is a dual full-bridge PWM motor driver manufactured by Allegro MicroSystems.

Specifications:

  • Output Current: Up to 1.5 A per bridge (continuous)
  • Operating Voltage: 4.5 V to 18 V
  • PWM Control: Supports high-frequency switching
  • Low RDS(ON) Outputs: Reduces power dissipation
  • Thermal Shutdown Protection: Prevents overheating
  • Undervoltage Lockout (UVLO): Ensures proper operation at low voltages
  • Logic Input Compatibility: 3.3 V and 5 V logic levels
  • Package Type: SOIC-16 (surface mount)

Descriptions:

The UDN6118A is designed for driving DC motors, stepper motors, and other inductive loads in applications such as robotics, automation, and industrial controls. It integrates two full H-bridges, allowing bidirectional motor control with PWM speed regulation.

Features:

  • Dual H-bridge configuration for driving two DC motors or a single stepper motor
  • Internal flyback diodes for inductive load protection
  • Efficient power management with low standby current
  • Wide operating voltage range for flexibility in different power supplies
  • Compact SOIC-16 package for space-constrained designs

For detailed electrical characteristics and application notes, refer to the official Allegro datasheet.
