TPS65090ARVNT

Overview

The TPS65090ARVNT is a single-chip power management IC designed for portable devices powered by dual or triple lithium-ion/polymer battery packs. It integrates a switch-mode battery charger with power path management, three high-efficiency buck converters (two fixed at 5V and 3.3V, one adjustable), two always-on LDOs, and seven load switches. The device supports I2C interface communication and features programmable charging currents up to 4A. Operating temperatures range from -40°C to 85°C in a 100-VQFN package.

Feature Summary

• Integrates switch-mode battery charger with JEITA-compliant thermal regulation and safety timers
• Includes three buck converters with low quiescent current for wide-load efficiency
• Provides seven individually controllable load switches with current limiting
• Supports multiple I2C speeds including Fast-Mode Plus and High-Speed modes

Applications

• Portable devices requiring integrated power path management
• Systems powered by 2-3 cell lithium-ion or lithium-polymer batteries
• Applications needing simultaneous AC adapter and battery operation
• Devices requiring multiple regulated voltage rails from a single PMIC

Procurement Notes

Verify the specific suffix ARVNT against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure compatibility with your system's I2C address configuration and thermal management strategy. Confirm that the 100-VQFN package dimensions align with your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a compact solution is needed for multi-rail power systems with integrated battery charging. It is suitable for designs where space is limited and multiple voltage domains must be managed efficiently. Consider the thermal performance of the exposed pad VQFN package for heat dissipation needs in enclosed environments.

Part Context

This part belongs to Texas Instruments' TPS6509x series of power management ICs. These devices are engineered for portable electronics, combining charging, conversion, and switching functions into a single chip to reduce board space and component count compared to discrete solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the TPS6509x family, such as the TPS65090ARVNR. Verify functional equivalence regarding output currents, voltage ranges, and control interfaces before substitution.
