The MAX5035BASA/V+T is a dual-channel buck switching regulator from Maxim Integrated. This device provides two independent high-side overcurrent limit circuit protection and load disconnect features from its integrated FET-dual Mosfet drivers. The device is designed for use in DC-DC converters, applications that require a high input voltage and high current, and where the cost and complexity of the conventional overcurrent sensing and shutdown is prohibitive. The device can be used in a wide range of converter architectures, including buck converter topologies, push-pull converters, and other more complex topologies such as flyback and dual-transistor (Cuk) converters.

The system requirements of this application are two-fold; firstly to provide overcurrent protection and second, load disconnect features. The overcurrent protection is implemented through a current sense resistor connected between the high-side driver and the load. The voltage across the resistance is sensed by the device and an appropriate threshold is set for the purpose of providing overcurrent protection. The load disconnect is provided through a shutdown FET switch integrated into the device. When activated, the switch disconnects the load from the input voltage, thus providing a safe and fast shutdown of the converter.

The MAX5035BASA/V+T is ideal for a wide range of applications, including automotive, industrial, consumer, and medical applications where a high input voltage and high current is required. It is also suitable for regulating power to high-voltage, low-power devices, and for use in battery-based applications. Additionally, the device\'s integrated FET-style Mosfet drivers ensure a robust and reliable solution for controlling the on/off state of the Mosfets.

The device is available in two versions, the MAX5035BASA and the MAX5035BASA/V+T. The MAX5035BASA is designed for applications that do not require the load disconnect feature, whereas the MAX5035BASA/V+T provides the additional benefit of load disconnect. The two versions are also available in a variety of packages, including DFN and SOT-223.

The MAX5035BASA/V+T operates in a fixed frequency mode, with a frequency of up to 1.0 MHz. The switching frequency can be adjusted using an external resistor, and the output voltage can be programmed using an external resistor divider. The device has a wide input voltage range, up to 80V, and an output voltage range of up to 70V. The device also provides an adjustable overcurrent threshold, adjustable overcurrent/load disconnect time delay, and adjustable power-on time delay.

In summary, the MAX5035BASA/V+T is the perfect solution for applications requiring dual-channel buck switching regulator and overcurrent protection and load disconnect features from an integrated device. It provides a versatile, low-cost, high-performance solution for applications that require high input voltage and high current. Its wide input voltage range, adjustable output voltage range, adjustable overcurrent threshold, adjustable overcurrent/load disconnect time delay, and adjustable power-on time delay make it ideal for a wide range of applications.
