MAX8730ETI+T is a power management integrated circuit (PMIC) that focuses on the battery charging of smartphones, tablets, and other portable consumer products. This PMIC contains a complete power management solution in a tiny package, making it suitable for applications that require a compact design. It offers a variety of features, including integrated boost regulation, current limit/ sense, USB port protection, and low standby power control. It also has a low EMI feature and is available in multiple package options from a 3 x 3 mm VQFN to a 5 x 7 mm RoHS-compliant MLF.

The MAX8730ETI+T works by providing regulated voltage or current to the battery, depending on the environment and current level. This PMIC uses a boost regulator to boost the input voltage when needed and increase the current to a level where it can charge the battery quickly. It also uses a current limit/sense circuit to monitor the current and limit it if it gets too high. Additionally, the MAX8730ETI+T has a USB port protection circuit that helps protect the input voltage and current pathways against over-voltage and over-current conditions. This circuit also helps prevent thermal issues caused by high-current conditions due to device overcharging.

The MAX8730ETI+T also includes a low standby power control circuit that helps conserve power when the device is not in active use. It monitors the input supply voltage and automatically enters a low-power mode whenever the device is inactive. This helps to extend the battery life of the device by reducing power consumption. Additionally, the PMIC includes an EMI filter that helps reduce EMI emissions from the charging device, thus making it more compliant with radio emission regulations.

In summary, the MAX8730ETI+T is a power management integrated circuit that is specifically designed for battery charging applications. It provides regulated voltage or current to the battery, and offers features like boost regulation, current limit/sense, USB port protection, low standby power control, and low EMI. It provides a comprehensive solution for battery charging and helps to extend battery life by reducing power consumption when the device is not in use. It is available in a variety of packages, making it suitable for applications that require a compact design.
