PMICs, or Power Management Integrated Circuits, are integrated circuits that provide the power management functions required by a variety of electronic systems. Battery chargers are one of the core components of PMICs, providing support for the charging of batteries used in mobile and embedded applications. The TPS65200YFFT is a PMIC battery charger that offers a flexible design for a variety of applications.

The TPS65200YFFT is a full-featured battery charger that offers features like automatic temperature protection, a recharge and hold feature, charger safety features, a high-accuracy current limit, flexible charge rates, and a low profile package for a wide range of performance and cost considerations. Additionally, the charger can be configured for both ultracapacitors and standard Li-ion battery cells in applications such as wireless sensor nodes, mobile phones, MP3 players, and consumer electronics.

The TPS65200YFFT offers three charging modes— Constant Current/Constant Voltage (CC/CV), Focused Constant Current (FCC) or Fast-Charge Constant Voltage (FCCV) without the need for user programming. In CC/CV mode, the charger will regulate the charge rate as the battery approaches its full capacity, and automatically switches to the lower voltage, lower current absorption mode to complete the charge cycle. In FCC and FCCV mode, the charger provides a steady state current or voltage to the battery, depending on the set parameters. This ensures an efficient charge while maintaining a precise current or voltage limit.

The TPS65200YFFT is highly configurable and provides many features to tailor the charge profile to the particular application. Temperature monitoring is supported by a number of temperature sensing options including an NTC temperature pin, and the charger can be configured for independent battery cell charging or simultaneous charging of a group of cells, as required.

Safety features are also supported by the TPS65200YFFT, including under-voltage and over-voltage protection, short circuit protection, over-temperature protection, and charge current detection. In order to protect the battery from overcharging, the charger is also capable of detecting outdated battery voltage or temperature readings, or when the charge current falls below a specified level.

The TPS65200YFFT is an example of a PMIC battery charger designed to support a wide range of applications. Its flexibility and parameter configuration capabilities make it ideal for use in mobile and embedded systems, providing a reliable and secure charging solution.
