Due to its high current capability, the module is frequently used in applications requiring direct current drive of motors and other loads. The IRAM336-025SB power driver module also has a wide input voltage range and is designed to meet challenges among harsh electromagnetic environments.

Working Principle

The IRAM336-025SB power driver module follows a four-stage power management principle. The first stage, the power supply stage, converts the input voltage range to a required output voltage range. The second stage, the power conditioning stage, up-conditions the output voltage to the needed output voltage, while providing EMC and temperature protection. The third stage, the power control stage, acts as a fault protection circuit and provides the output current regulation. The fourth and final stage, the power output stage, converts the regulated voltage to a regulated output current, providing contactless and low power dissipation operation.

The power train control stage of the module includes an optimal current detection circuit, providing fast and accurate current sensing for the device. This current detection circuit also provides full cycle protection, ensuring protection in the event of a loss of signal. The module also includes an on-chip CRC generator, providing EMC protection to the module. The module also features a Fault Condition Device (FCD) signal output, providing an error signal output in the event of a system fault. The module also features an oversized power discharging switch, providing full system protection in the event of an unexpected power loss.
