Product details
Overview
TEA19051BAATK/1J from NXP Semiconductors is a secondary-side USB-PD 3.0/PPS and QC4+ controller IC for high-efficiency SMPS adapters, supporting CV/CC regulation with ±2 % voltage/current accuracy, 2.9–21 V output range, and <30 mW no-load power. It integrates USB-PD PHY, charge pump for NMOS gate drive (SW pin), fast discharge (DISCH), and dual GPIO-based NTC temperature sensing for adapter/cable monitoring.
For engineers reviewing the TEA19051BAATK/1J datasheet, TEA19051BAATK/1J pinout, TEA19051BAATK/1J application, or TEA19051BAATK/1J equivalent, key selection criteria include USB-PD 3.0 + PPS compliance, hardware-enforced protections (OTP/OVP/OCP/OSP), HVSON16 package compatibility, and MTP-programmable PDO configuration for multi-protocol charging.
Technical Context
The TEA19051BAATK/1J implements a digitally controlled analog feedback architecture where VSNS and ISNS pins feed dedicated 12-bit DAC (voltage) and 10-bit DAC (current) loops, enabling precise CV/CC regulation independent of host MCU execution. Its embedded ROM/RAM/MTP microcontroller manages protocol state machines for USB-PD 3.0 (including PPS), QC4+, BC1.2, and Type-C v1.3 detection-all with hardware-backed safety logic.
Protection functions-including adaptive OVP/UVP, dual external OTP via GPIO1/GPIO2, and output short protection (<50 mW dissipation)-are implemented in dedicated analog hardware, ensuring fail-safe operation even during firmware lockup. The SW pin delivers VCC + 6 V gate drive using an internal charge pump, while DISCH provides controlled Vbus ramp-down compliant with USB-PD vSafe0V requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-PD + QC secondary-side controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Single-protocol USB-PD 3.0 controller only; no QC/BC support; requires external MCU for PPS control | Limited to USB-C ecosystems without legacy QC/BC device support | Choose when USB-PD-only functionality suffices and cost-per-watt is prioritized over multi-protocol flexibility |
| MPQ4282GQ-A | Integrated buck-boost converter with embedded PD controller; no separate SW/DISCH pins; fixed 16-pin QFN | Targeted at all-in-one monolithic adapters rather than discrete SMPS designs with TEA193x/TEA199x pairing | Prefer when board space is constrained and primary/secondary integration reduces layout complexity |
Compared with STUSB4500QTR and MPQ4282GQ-A, the TEA19051BAATK/1J uniquely combines full USB-PD 3.0 + PPS, QC4+, and BC1.2 in a discrete controller architecture optimized for high-power, thermally managed SMPS with hardware safety independence - making it the only option supporting NXP's complete TEA19xx ecosystem co-design.

FAQ
What USB-PD and QC protocols does the TEA19051BAATK/1J support?
The TEA19051BAATK/1J supports USB-PD 2.0 and 3.0 including Programmable Power Supply (PPS), Qualcomm QuickCharge QC2.0, QC3.0, and QC4+, plus Battery Charging 1.2 (BC1.2). All protocols are implemented in hardware with dedicated CC1/CC2 and DP/DM interfaces, and MTP-programmable PDOs allow field-upgradable configurations without changing the TEA19051BAATK/1J silicon.
How does the TEA19051BAATK/1J achieve <30 mW no-load power?
The TEA19051BAATK/1J achieves <30 mW system-level no-load power through intelligent circuit gating, ultra-low quiescent current design, and optimized startup sequencing - including zero optocoupler current at initial power-on and rapid transition to minimal active mode before attach detection. This meets CoC Tier-2, EuP Lot 6, and DOE Level VI efficiency mandates without auxiliary winding or external bias circuits.
What protections are implemented in hardware versus firmware on the TEA19051BAATK/1J?
All critical protections - including overtemperature (OTP), overvoltage (OVP), undervoltage (UVP), output short (OSP), open-supply (OSUP), and open-ground (OGP) - are implemented in dedicated analog hardware on the TEA19051BAATK/1J. Only UVP can be disabled via MTP settings; all others remain fully functional even if the embedded MCU locks up, ensuring fail-safe operation per USB-IF and IEC/UL safety requirements.
Can the TEA19051BAATK/1J be used with NXP's TEA193x primary controller and TEA199x SR controller?
Yes, the TEA19051BAATK/1J is explicitly designed to operate in conjunction with NXP's TEA193x quasi-resonant/DCM primary controllers and TEA199x synchronous rectifier controllers. This co-optimized ecosystem enables ultra-high efficiency (>94 % at full load), precise cross-regulation, and coordinated safety response - all documented in NXP application notes AN11719 and AN11922 for the TEA19051BAATK/1J.
What is the function of the SW and DISCH pins on the TEA19051BAATK/1J?
The SW pin provides charge-pump boosted (VCC + 6 V) gate drive for an external high-side NMOS load switch, while the DISCH pin integrates a low-RDS(on) switch to rapidly discharge Vbus through an external resistor - both are essential for USB-PD vSafe0V compliance. The TEA19051BAATK/1J uses these pins to meet hard-reset timing requirements without relying on software-controlled GPIO toggling.
