The TPS659161RGZR is a highly integrated power management integrated circuit (PMIC) from Texas Instruments, designed to cater to a broad range of applications, including smartphones, tablets, and other portable electronics. This advanced PMIC combines a multitude of features that enable it to provide efficient power management solutions for systems powered by single-cell Li-ion or Li-polymer batteries.

Key Features

• Multiple Power Rails: The device includes several DC/DC converters, LDOs (Low Drop-Out regulators), and switchable power supplies, allowing it to generate various voltage rails required by complex systems.
• Programmable Voltage: Many of the power outputs are programmable, enabling fine-tuning to meet specific system requirements and optimize power consumption.
• SmartReflex™ Technology: This adaptive voltage scaling technology allows the device to dynamically adjust power levels for improved power efficiency and extended battery life.
• Integrated Power Sequencing: The TPS659161RGZR comes with an integrated power sequencer, simplifying system design by managing the power-up and power-down sequences for the various power rails.
• I2C Interface: An I2C interface enables system software to control and monitor the PMIC, providing the flexibility to adjust settings and respond to system conditions in real-time.

Advanced Protection

With built-in safety features, the TPS659161RGZR ensures reliable operation under various conditions. It includes over-voltage, under-voltage, over-current, and thermal protection circuits. These protective measures safeguard both the PMIC and the system it powers from electrical mishaps.

Compact Design

The device comes in a compact 48-pin QFN (RGZ) package, which is ideal for space-constrained applications. Its small footprint does not compromise its performance or the breadth of its integrated features, making it a preferred choice for designers looking to maximize functionality in limited spaces.
