7Semi Vikram 3020D High-Current Dual-Channel Brushed DC Motor Driver with 7–32V Input and 20A per Channel
The 7Semi Vikram 3020D is a high-current dual-channel motor driver designed to independently control two brushed DC motors from a 7–32V DC motor supply. Each channel uses a discrete high-current H-bridge power stage and provides dedicated direction and PWM control, allowing independent adjustment of motor direction and speed. With up to 20A continuous current per channel, the module is suitable for differential-drive robots, automated guided vehicles, mobile robotic platforms, industrial actuators, and other demanding motion-control systems.
Each motor channel also supports short-duration peak currents up to 80A for a maximum of 1 second. The control interface accepts both 3.3V and 5V logic levels and supports PWM frequencies up to 20kHz, simplifying integration with Arduino, ESP32, STM32, RP2040, and other embedded controllers. Integrated overcurrent, overvoltage, VM undervoltage lockout, and thermal-shutdown functions help protect the power stage, with thermal shutdown specified at 120°C.
