TEA19051BAATK/1J

Controllers Overview

The TEA19051BAATK/1J is a highly configurable secondary side SMPS controller supporting USB-PD 2.0/3.0, QC 2.0/3.0/QC4+, 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 CV and CC modes. The device features an embedded MCU with MTP memory, integrated charge pump for NMOS load switch drive, and fast output discharge capability. It achieves ultra-high efficiency and very low no-load power (< 30 mW) while requiring only a single optocoupler for regulation.

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 hardware-implemented protections such as adaptive OVP, UVP, OTP, and short circuit protection for fail-safe operation.
• Features precise analog control loops with 12-bit DAC for voltage and 10-bit DAC for current regulation.
• Includes dedicated pins for external temperature monitoring via NTC sensors and internal die temperature sensing.

Controllers Applications

• USB chargers for smartphones and tablets supporting Qualcomm QuickCharge QC2.0, QC3.0, and QC4+.
• USB-PD 3.0 Type-C chargers with optional VDM support for mobile devices.
• High-power adapters requiring CoC Tier-2 and DOE v6 efficiency compliance.

Controllers Procurement Notes

Verify the specific suffix '1J' against the manufacturer's official ordering information table to confirm factory configuration parameters. Ensure compatibility with primary side controllers like the TEA193x series and synchronous rectifier controllers from the TEA199x family for complete system integration.

Controllers Selection Notes

Select this component for applications requiring high digital integration and minimal external components. Consider the HVSON16 package constraints and verify that the required PDOs fit within the seven available slots in the non-volatile memory. Ensure the design accommodates the single optocoupler requirement for the feedback loop.

Controllers Part Context

This part belongs to the TEA19051BTK family of secondary side controllers designed for smart charging applications. It serves as a programmable replacement for traditional shunt regulators like the TL431, offering enhanced protocol support and safety features through its embedded microcontroller architecture.

Controllers Replacement Considerations

Direct replacements are limited due to the specific factory-configured nature of the BAA variant. Verify if other suffixes within the TEA19051BTK family (e.g., BABTK, BACTK) offer compatible default PDO configurations or if custom MTP programming is feasible for alternative parts.
