TEA19051BAKTK/1J

Controllers Overview

The TEA19051BAKTK/1J is a highly configurable secondary side SMPS controller designed for USB-PD 2.0, USB-PD 3.0, QC 2.0, QC 3.0, and QC 4+ protocols. It supports USB Type-C v1.3 and BC1.2 standards within a low-cost HVSON16 package (SOT1308-1). The device features an embedded MCU with MTP memory, enabling precise voltage regulation via a 12-bit DAC and current control via a 10-bit DAC. It operates in a wide output voltage range of 2.9 V to 21 V, achieving better than 2% accuracy in both CV and CC modes. The system solution delivers extremely low no-load power below 30 mW, meeting stringent efficiency requirements.

Controllers Feature Summary

• Integrates USB-PD physical interface and Type-C detection hardware for reliable protocol communication
• Provides continuous output voltage and current measurement with high precision digital control loops
• Includes dedicated hardware protections implemented independently of the microcontroller for fail-safe operation
• Features an internal charge pump to directly drive external NMOS load switches

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
• High-power adapters requiring strict safety compliance and low standby power consumption

Controllers Procurement Notes

Verify the specific factory configuration programmed into the non-volatile MTP memory before integration. Confirm that the ordering suffix matches the required default voltage and current settings for your application design. Ensure compatibility with the primary side controller and synchronous rectifier components for optimal system performance.

Controllers Selection Notes

Select this component when designing compact smart chargers that require integrated protocol handling and minimal external component count. Evaluate the available PDO configurations stored in MTP against target device requirements. Consider the thermal management needs associated with the HVSON16 package during high-power operation scenarios.

Controllers Part Context

This part belongs to the TEA19051BTK family of secondary side controllers manufactured by NXP Semiconductors. The BA variant specifically denotes a factory-configured version optimized for standard charging applications. It serves as a programmable replacement for traditional shunt regulators like the TL431, consolidating feedback and protocol logic into a single integrated circuit.

Controllers Replacement Considerations

Direct replacements include other variants within the TEA19051BTK series such as TEA19051BAATK/1 or TEA19051BABTK/1. Verify that the alternative part number possesses the identical MTP configuration parameters to maintain electrical compatibility without redesigning the firmware or resistor dividers.
