7Semi Vikram 3230 High-Current Single-Channel Brushed DC Motor Driver with 7–32V Input and 30A Continuous Output
The 7Semi Vikram 3230 is a high-current single-channel motor driver designed to control one brushed DC motor from a 7–32V DC motor supply. Its discrete high-current H-bridge power stage provides bidirectional forward and reverse motor control, while dedicated direction and PWM inputs allow straightforward adjustment of motor direction and speed. The module supports up to 30A continuous motor current and short-duration peak currents up to 100A for a maximum of 1 second.
The control interface supports both 3.3V and 5V logic levels, enabling connection to Arduino, ESP32, STM32, RP2040, and other embedded controllers. PWM operation up to 20kHz provides flexible speed control, while overcurrent, overvoltage, VM undervoltage-lockout, and thermal-shutdown functions help protect the power stage during abnormal operating conditions. The thermal-shutdown threshold is specified at 120°C.
