L6206PD DMOS dual full-bridge motor driver — 52V 2.8A, PowerSO36
The L6206PD is a DMOS dual full-bridge motor driver IC from STMicroelectronics, realised in BCD technology that integrates isolated DMOS power transistors with CMOS and bipolar circuits on a single chip. Rated at 8–52V supply voltage and 2.8A continuous output current (5.6A peak), it is designed for driving DC motors, stepper motors, and other inductive loads in robotics, industrial automation, and embedded motor control systems. The PowerSO36 package provides excellent thermal performance for sustained operation.

Key Features:
- Dual full-bridge (H-bridge) — drive two DC motors independently or one bipolar stepper motor
- Programmable high-side overcurrent detection — non-dissipative, protects the load and driver
- Diagnostic output — easy fault detection and overcurrent protection implementation
- Paralleled operation — combine both bridges for up to 5.6A DC on a single motor
- Cross conduction protection — prevents shoot-through on bridge switching
- Thermal shutdown — automatic protection against overtemperature
- Undervoltage lockout (UVLO) — prevents operation below safe supply voltage
- Integrated fast freewheeling diodes — no external diodes required
- Up to 100kHz PWM frequency — smooth motor speed control
Applications:
- DC motor speed and direction control
- Bipolar stepper motor driving
- Robotics and autonomous vehicle motor control
- Industrial automation actuators
- CNC machine axis drivers
- Printer and scanner carriage motors
Note: The PowerSO36 package requires a PCB with exposed pad or heatsink connection for adequate thermal dissipation at full load. Refer to the STMicroelectronics L6206 datasheet for PCB layout guidelines.
