High Current Half Bridge with Over-Current Shutdown

This high-current half-bridge driver board is designed as a flexible, open-design platform that can be configured to meet a wide range of voltage, current, and switching-frequency requirements. The board includes an adjustable overcurrent protection circuit, allowing users to set the desired current limit by selecting an appropriate shunt resistor value and adjusting the onboard threshold trimmer.

An onboard current-sense shunt resistor is provided for over-current detection. Users can select the shunt resistor value according to the required current threshold. Gate resistors and optional gate-drive diodes can also be customized to optimize switching performance for specific PWM frequencies and load characteristics.
