These applications include electric vehicles, roof top photovoltaic (PV) systems, unmanned aerial vehicles (UAVs), electric boats, scheduled smart charging, and other Li-Ion/Li-Po rechargeable battery packs.

The MAX72044B+ is designed to provide the highest power density for a variety of applications including: automotive, electric vehicle, portable medical equipment, UPS, renewable energy, and robotics. The device is optimized to achieve the highest power performance and reduce the size of the power stack. It additionally provides a cost-effective solution for a wide range of high power applications.

Working Principle

The MAX72044B+ is composed of a traction simulation circuit and a multicell voltage regulator. The traction simulation circuit allows for the connection of up to 8 cells in series and provides independent cell monitoring. The traction simulation circuit uses two boost converters to achieve a regulated current output. Safety features include overvoltage protection and low-current indication to prevent overcurrent or thermal runaway.

The multicell voltage regulator is a true buck-boost converter that is optimized to increase the efficiency in a wide range of operating conditions. It is capable of operating from 6V to 400V while providing an output voltage range of 4.5V to 400V. The multicell voltage regulator has an internal foldback capability, thus preventing short circuit conditions. Additionally, it features soft-start capabilities, programmability of overvoltage trip point, and thermal limit protection.

The MAX72044B+ also provides cell balancing for up to 8 cells in series. The cell balancing features measure and balance all cell voltages simultaneously, eliminating the need for external balance mechanisms. Additionally, the MAX72044B+ includes an external safety mechanism to prevent the cells from overcharging or discharging.

In summary, the MAX72044B+ is a fully integrated multicell battery front-end solution for a wide range of applications. It is designed to provide the highest power density for a variety of applications while reducing the size of the power stack. It is optimized for automotive, electric vehicle, portable medical equipment, UPS, renewable energy, and robotics applications. Additionally, the device provides cell balancing and a range of safety features for overvoltage protection and low-current indication.
