MAX1736ETT42+T is an advanced and highly integrated power management integrated circuit (PMIC) designed for battery charging applications. This PMIC combines a high-efficiency, fixed-frequency, buck charge regulator and a dual Li+ battery stack protector in a single device. It is also integrated with full diagnostic monitoring and precision end-of-charge regulation.

The MAX1736ETT42+T PMIC has been designed for battery charging applications for mobile devices and other consumer electronics such as tablet PCs, digital cameras, camcorders, and portable media players. It is designed to provide accurate and robust charging performance under a variety of conditions and applications, such as those with low battery voltage, and those with high current draw.

The MAX1736ETT42+T is an ideal solution for mobile devices and other consumer electronics as it helps to protect the battery from overcharging, over-temperature, and over-voltage while providing an accurate and safe charging process. It also helps to reduce design complexity and save space by combining multiple functions into one package.

The MAX1736ETT42+T features a low voltage adapter that helps to reduce the power consumption of the battery system, and a high-current capability that provides a fast and efficient charging process. It also provides power isolation, reverse polarity and short circuit protection, and under-voltage protection. The PMIC also includes a selectable charge current setting for both Li+ batteries and USB ports.

The MAX1736ETT42+T PMIC operates according to the “Joule” (J) or “Coulomb” (C) charge control method. In the Joule charging method, the PMIC calculates the average current over a specified sampling period and then calculates the charge rate based on the determined average current. This control method conserves energy by limiting the input current during heavy charging periods, reducing total power consumption. In the Coulomb charge control method, the PMIC charges the battery with the regulated voltage at the same rate of power input, allowing the charging current to vary depending on the cell charge capacity.

The MAX1736ETT42+T also integrates a separate Li+ battery stack protector that monitors and protects both cell stacks. It monitors the cell stack voltage, temperature and current draw from each cell stack and shuts off in the event of an overcharge, short-circuit, or over-load. This ensures that the battery system remains safe and secure.

The MAX1736ETT42+T provides a wide operating input voltage range and allows for a wide range of charging applications. It also supports a wide range of battery types, including NiCd, NiMH, Li-Ion and Li-Polymer. Additionally, the PMIC is compatible with both 5V and 12V charging adapters. It is also equipped with an over-temperature protection feature that shuts off charging when it detects high battery temperatures.

The MAX1736ETT42+T PMIC is ideal for a wide range of applications, providing an advanced power solution with accurate charging performance, high-efficiency, and superior protection. Its rich set of features and safety functions make it suitable for a wide range of consumer electronics and portable devices.
