The TPS65217BRSLR is a highly integrated power management IC (PMIC) from Texas Instruments (TI), designed to support a wide range of applications including portable electronics, embedded systems, and industrial devices. This versatile chip is ideal for systems powered by a single Li-Ion or Li-Polymer cell, which can range from 2.5V to 5.5V. It can also operate from an external 5V adapter or a USB input.
This PMIC integrates multiple power rails and features to ensure the reliable operation of the host system. It provides three step-down converters (buck), one boost converter, and four low-dropout regulators (LDOs). These power outputs are highly efficient and can be sequenced and configured via an I2C interface, which allows for a flexible and optimized power management scheme tailored to the specific needs of the application.
The TPS65217BRSLR is designed with safety in mind, featuring a range of protective measures such as overvoltage, undervoltage, and overcurrent protection. It also includes a battery temperature monitoring input, which can be crucial for portable devices that require precise battery management to ensure safety and longevity.
An additional feature of this PMIC is its power sequencing capability. The TPS65217BRSLR can manage the power-up and power-down sequences for the attached subsystems, which is essential for complex electronics where certain components must be powered in a specific order to ensure proper operation.
The TPS65217BRSLR comes in a compact 48-pin VQFN package, which is suitable for space-constrained applications. It is also characterized for operation over a broad temperature range, making it a robust choice for both consumer and industrial environments.
Whether you're developing a handheld device, a smart wearable, or a sophisticated industrial control system, the TPS65217BRSLR provides a comprehensive solution for power management, simplifying the design process and enhancing overall system reliability.
