TEA19032BAAT/1J

Controllers Overview

The TEA19032BAAT/1J is a highly configurable secondary side Switch Mode Power Supply (SMPS) controller manufactured by NXP USA Inc. It supports USB Type-C v.1.3, USB Power Delivery (USB-PD) 2.0 and 3.0 including Programmable Power Supply (PPS), and Qualcomm QuickCharge QC4 protocols. The device operates within a supply voltage range of 2.9 V to 21 V with a typical supply current of 3 mA. It features Constant Voltage (CV) accuracy better than 2% and Constant Current (CC) accuracy better than 2%. The component is housed in a 10-SOIC package (SOT1437-1) and functions as a programmable replacement for TL431 shunt regulators.

Controllers Feature Summary

• Integrates USB-PD physical interface (PHY) and Type-C detection logic for direct protocol handling without external microcontrollers.
• Includes an internal charge pump to drive an external NMOS load switch directly, eliminating the need for additional gate driver circuitry.
• Provides hardware-implemented safety protections including overvoltage, overcurrent, and overtemperature safeguards independent of processor actions.
• Features embedded MCU with non-volatile MTP memory for storing system configuration parameters and power data objects.

Controllers Applications

• USB chargers for smartphones and tablets supporting Qualcomm QuickCharge QC4 protocol
• USB-PD 3.0 Type-C chargers with optional Vendor Defined Message support
• High-power adapters requiring fail-safe overload protection

Controllers Procurement Notes

Verify component authenticity through authorized NXP distributors or certified partners. Confirm the specific suffix /1J matches the required tape and reel packaging format. Check the manufacturing date code against project timelines to ensure compatibility with assembly schedules. Request original datasheets and RoHS compliance certificates during the sourcing process to validate regulatory adherence.

Controllers Selection Notes

Select this controller when designing secondary-side regulation for AC-DC converters requiring USB-PD 3.0 or QC4 support. Ensure the primary side controller, such as the TEA193x series, is compatible with the optocoupler feedback loop. Verify that the application requires a low pin count solution to minimize printed circuit board space. Consider the thermal management requirements given the operating temperature range and integrated protection features.

Controllers Part Context

This component belongs to the TEA19032BT family of smart charging controllers designed for high-efficiency power supplies. It complements primary side controllers like the TEA1936x and synchronous rectifier controllers from the TEA199x series. The device enables compact form factors by reducing the bill of materials and meeting strict energy efficiency standards such as CoC Tier-2 and DOE Level VI.

Controllers Replacement Considerations

Direct replacements are limited due to factory-configured versions. Evaluate the TEA19031AT for similar secondary side control applications if available. Verify pinout compatibility and software configuration differences before substituting. Consult NXP documentation for cross-reference recommendations regarding updated product lines.
