The MAX14936AWEVKIT# is an evaluation and demonstration board and kit designed by Maxim Integrated, used to evaluate and demonstrate the features of their MAX14936A IC. It is an automotive-grade powertrain solution for motor-in-vehicle applications such as power steering systems. The MAX14936AWEVKIT# includes one evaluation board and one power supply board, each containing a single MAX14936A IC. The IC has two main functions: it provides both power-switch and current-sense functionality. This allows it to be used for both power-distribution and motor-current sensing applications.

The power-switch aspect of MAX14936AWEVKIT# has a wide range of applications, including usage as an H-bridge driver, allowing it to control the current-flow in motors. It also can be used in switching regulators, dc to dc converters, and battery chargers. It can also be used as a variable-voltage controller, providing power to different components for each subsystem.

The motor-current-sensing aspect of the MAX14936AWEVKIT# is also very useful. It accurately measures the current and signals the level of current at which the system needs to be shut down. This allows the system to be shut down automatically when the current reaches a certain level, preventing the system from incurring damage due to over current. The MAX14936AWEVKIT# is especially useful in applications that require motor shutdown in case of over current, such as in power-steering systems.

The working principle of MAX14936AWEVKIT# is relatively simple. The MAX14936A IC includes two channels, each with a current-sense amplifier. One channel is used to measure the current in the negative direction and the other measures the current in the positive direction. By comparing the two measurements, the MAX14936AWEVKIT# can determine if the current is within the safe, acceptable range. If the current is too low or too high, it will quickly shut off the system, preventing any damage.

In addition, the MAX14936AWEVKIT# also includes a small LCD display which can be used to monitor the current levels of the system. This can be done via the manual settings or the IC can be programmed to automatically shut the system off when the current exceeds the set threshold. This ensures safety and allows engineers to easily monitor the system and identify any problems.

In conclusion, the MAX14936AWEVKIT# is an excellent IC suitable for a wide range of applications. Its power-switch and current-sense features make it an ideal solution for motor applications, especially power steering and motor shutdown systems where reliability is important. Its easy-to-use LCD display makes it convenient to monitor current levels, and its two current-sense amplifiers enable it to quickly and accurately detect if the current is too high or too low.
