TSM1011AIST

PMIC - Battery Charger technology is one of the most important advances in the field of power electronics. The TSM1011AIST is a PMIC (Power Management Integrated Circuit) which is specifically designed for battery charging applications. This article will discuss the application field of the TSM1011AIST and its working principles.

The TSM1011AIST is an advanced power management integrated circuit which provides a high efficiency, low BOM and low EMI combination for battery charging applications. The TSM1011AIST is an ideal choice for charging Lithium-Ion, Polymer and Nickel Metal Hydride batteries. It provides multi-mode charging, with manual voltage selection, and features such as input current limiting and temperature compensation for improved charger performance.

The TSM1011AIST integrates two low drop-out linear regulators, two Pulse Width-Modulation (PWM) controllers and one linear current limiter. The linear regulators provide simple and accurate constant current/constant voltage regulation for battery charging. The PWM controller provides programmable constant-current control, enabling efficient operation over a wide range of input voltage. The linear current limiter provides constant current charging to ensure safe operation within the specified parameters.

The TSM1011AIST is also designed to deliver an extremely high efficiency, up to 95%, at a frequency of 4.4MHz. This high efficiency results in a low heat dissipation and therefore a low total cost of ownership. The TSM1011AIST operates over a temperature range of -40 to 85°C, and its wide voltage range of 4.2--16.5V allows it to be used in a wide range of battery types and chemistries. The IC is also highly reconfigurable, with a range of programmable options for setting the input current limit, and for regulating output voltage. Finally, the TSM1011AIST also features thermal protection and short-circuit protection mechanisms.

In conclusion, the TSM1011AIST is a highly efficient and cost-effective PMIC specifically designed for battery charging applications. It offers a wide range of features and options, including multi-mode charging, automatic voltage selection, input current limiting, temperature compensation and thermal and short-circuit protection. With its high efficiency, wide range of supported chemistries and temperatures, and configurable features, the TSM1011AIST is an ideal choice for applications requiring battery charging.
