TEA19051BACTK/1J

Controllers Overview

The TEA19051BACTK/1J is a 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 and provides precise regulation with better than 2% accuracy for both constant voltage and constant current modes. The device features a 12-bit DAC for voltage control and a 10-bit DAC for current control. It utilizes an HVSON16 package (SOT1308-1) and incorporates an embedded MCU with MTP memory for system configuration.

Controllers Feature Summary

• Supports multiple fast-charging standards including USB Type-C v1.3, USB Power Delivery, and Qualcomm QuickCharge protocols.
• Integrates hardware-implemented protections such as overtemperature, overvoltage, and short-circuit protection independent of the microcontroller.
• Features a dedicated charge pump to drive external NMOS load switches directly from the SW pin.

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 against the required application parameters before procurement. Confirm that the ordering suffix matches the intended PDO settings and protocol enablement. Ensure compatibility with primary side controllers like the TEA193x series for complete system integration.

Controllers Selection Notes

Select this component for designs requiring high integration and low no-load power consumption. Verify that the HVSON16 package fits the thermal and spatial constraints of the target PCB layout. Ensure the design accommodates the necessary external components for the optocoupler feedback loop and sense resistors.

Controllers Part Context

This part belongs to the TEA19051BTK family of highly configurable secondary side controllers. It serves as a programmable replacement for traditional shunt regulators like the TL431, offering enhanced digital integration and protocol support within a compact form factor suitable for modern smart charging applications.
