MAX17080GTL+T is an advanced, wide input voltage range, high-efficiency battery charging controller that integrates many different device functions into a single IC. This device is designed to support multiple-cell Li-ion and Li-polymer battery chargers for portable applications. The device includes a powerful current source for linear or pulse charging, or for current limiting or power buildup. It also includes a thermal-control loop (TSD) to protect the battery from overheating, and a temperature sensor for accurate temperature readings.

The MAX17080GTL+T is well suited for automotive, communication, industrial, and consumer applications. It is compatible with low-power 5V and 7.5V chargers as well as high-power 12V, 24V, and 48V chargers. It also provides a variety of protections to ensure the safe use of the battery. These protections include over-voltage, under-voltage, short-circuit, and over-temperature protection.

The key features of the MAX17080GTL+T include an efficient two-phase power switching architecture with a low quiescent current at no-load and standby, an adjustable voltage output up to 6V, and a high-accuracy current sense amplifier with two outputs. It also offers a wide range of current limits to best suit a variety of battery designs. Finally, it offers extensive protection features, including over-temperature, short-circuit, overload, over-charge, and over-discharge protection.

The working principle of the MAX17080GTL+T is based on a two phase PWM architecture. The controller first converts the analog input voltage and current into trim digital values and then amplifies them. This amplified signal is used to control the switches in the power supply. The controller then senses the current flow to the battery and regulates the power to the battery in a closed-loop fashion to ensure proper charging. The MAX17080GTL+T also uses an adjustable voltage reference to set the output voltage of the charger. Finally, the controller monitors the temperature of the battery and adjusts the duty cycle of the switches accordingly to ensure stability and safety.

In conclusion, the MAX17080GTL+T is an advanced battery charger controller designed for a variety of applications. It features a wide voltage range and an efficient two-phase power switching architecture and offers an adjustable output voltage up to 6V. In addition, it provides extensive protection features, including over-temperature, short-circuit, overload, over-charge, and over-discharge protection. Finally, it offers a range of current limits to best suit a variety of battery designs.
