TEA19051BAGTK/1J

Controllers Overview

The TEA19051BAGTK/1J is a secondary side controller for switch mode power supplies (SMPS) supporting USB-PD 2.0/3.0, QC 2.0/3.0/4+, and BC1.2 protocols. It operates within a wide output voltage range of 2.9 V to 21 V with better than 2% accuracy in both constant voltage and constant current modes. The device features an embedded MCU with non-volatile MTP memory, integrated charge pump, and hardware-implemented protections including overtemperature, overvoltage, and short circuit protection. It utilizes a low-cost HVSON16 package (SOT1308-1) and requires minimal external components.

Controllers Feature Summary

• Supports multiple fast-charging standards including USB Type-C v1.3, USB-PD 3.0 with PPS, and Qualcomm QuickCharge protocols.
• Integrates an embedded microcontroller with non-volatile multi-time programmable memory for flexible system configuration.
• Provides comprehensive hardware-based safety protections independent of processor actions to ensure fail-safe operation.
• Features dedicated pins for driving external NMOS load switches and enabling fast output discharge.

Controllers Applications

• USB chargers for smartphones and tablets supporting Qualcomm QuickCharge protocols
• USB-PD 3.0 Type-C chargers with optional vendor-defined message support

Controllers Procurement Notes

Verify the specific factory-configured version required, as the TEA19051BTK family includes multiple variants with predefined parameters stored in MTP memory. Confirm that the ordering suffix matches the desired default output voltage and current settings. Ensure compatibility with the primary side controller and synchronous rectifier controller for the complete SMPS solution.

Controllers Selection Notes

Select this controller for high-power adapters requiring precise voltage and current regulation with low no-load power consumption. Consider the HVSON16 package for applications needing a small form factor. Evaluate the need for specific protocol support such as PPS or QC4+ when defining the MTP configuration requirements.

Controllers Part Context

The TEA19051BAGTK/1J belongs to the TEA19051BTK family of highly configurable secondary side SMPS controllers. This family is designed to work in combination with primary side controllers like the TEA193x series and synchronous rectifier controllers from the TEA199x series to build complete smart-charging solutions.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The TEA19051BTK family offers various factory-configured versions; verify if another variant within the same family meets the specific application requirements before seeking external replacements.
