TDA168462HKLA1 is a PMIC (Power Supply Controllers, Monitors) device from Texas Instruments. It is designed to provide high-efficiency, reliable, and cost-effective power management for mobile devices, including notebook and tablet PCs. Compared to lower cost controllers, the TDA168462HKLA1 enables greater design flexibility and faster, simpler development of high-efficiency power management solutions.

The TDA168462HKLA1 integrates power-management features in one device including a DC-DC converter, linear regulators, switching, FET drivers, overvoltage protection, battery charging, and more. It supports lithium-ion (Li-Ion) batteries, nickel-cadium (Ni-Cd) batteries, and also can be configured for universal charging of up to 10 different types of batteries. The integrated error amplifier supports a wide range of inputs, enabling high efficiency in both buck and boost converters. In addition, the TDA168462HKLA1 supports hot-plug and brown-out protection for enhanced system safety.

The TDA168462HKLA1 offers a complete range of power management features. It integrates many independent DC-DC converters and linear regulators to provide power efficient and reliable power distribution. There are four independent switching and linear regulators to support up to four independent voltage rails including a main system voltage rail (Vaux). For better system performance, the TDA168462HKLA1 offers a range of adjustable soft-start and dynamic voltage scaling features. It also includes digital control, power-save logic, and over-voltage protection features to further enhance system reliability.

The TDA168462HKLA1 also offers FET drivers and over-current protection. The FET driver can be used to drive low-side or high-side FETs to control the current in an external switching regulator or battery charger. The device also supports a range of programmable over-current protection levels, helping to protect against drastic currents and increasing system safety.

The integrated battery charging controller supports up to 10 different battery types, allowing for universal charging. The charger supports a range of charging methods, including pulsed charging, fast charging, charging from an external power supply, and other proprietary charging methods. The device also supports USB charging for universal mobile charging.

The TDA168462HKLA1 also includes a comprehensive set of power-save features. It supports five different power saving modes, including Auto/Sleep/Stop/Standby/Shutdown. In Standby mode, the device can be used to sequence multiple rails and reduce system power consumption. The device also includes a small reserve of power to keep the system running while the rest of the system is shutdown.

In conclusion, the TDA168462HKLA1 is a high-efficiency and cost-effective power management solution for mobile devices. It offers a complete range of power management features including DC-DC converters, linear regulators, FET drivers, overvoltage protection, battery charging, and more. Additionally, its wide variety of power-saving features and universal charging capability make it a great choice for increasing system efficiency and prolonging system runtime.
