Product details
Overview
TEA19051BAAT/1J from NXP Semiconductors is a secondary-side USB-PD 3.0/PPS and QC4+ controller IC for AC-DC SMPS, supporting CV/CC regulation with ±2 % output voltage and current accuracy, 2.9–21 V programmable output range, and integrated USB-C CC1/CC2 PHY, DP/DM interface, and NMOS gate driver (SW pin). It enables compact, CoC Tier-2/EuP Lot6-compliant 65 W+ chargers.
For engineers reviewing the TEA19051BAAT/1J datasheet, TEA19051BAAT/1J pinout, TEA19051BAAT/1J application, or TEA19051BAAT/1J equivalent, key selection considerations include its hardware-enforced protections (OTP, OVP, OSP), MTP-programmable PDOs (up to 7, including 4 PPS), dual GPIO temperature sensing, and single-optocoupler feedback architecture.
Technical Context
The TEA19051BAAT/1J implements a digitally controlled analog CV/CC loop: VSNS senses output voltage via resistor divider (MTP-matched ratios: 1/2.5, 1/5.476, or 1/8.325), while ISNS monitors current through an external sense resistor (2–22 mΩ) amplified 50× internally. Regulation commands are executed via USB-PD (CC1/CC2) or QC (DP/DM), with DAC resolution of 12-bit (voltage) and 10-bit (current).
Its protection architecture is fully hardware-based - including adaptive OVP/UVP, OTP (internal + two external), OSP, and soft-short detection on CC1/CC2 - ensuring fail-safe operation independent of firmware execution. The SW pin drives an external NMOS load switch using an internal charge pump (VCC + 6 V), and DISCH provides controlled Vbus discharge to vSafe0V (<0.8 V) per USB-PD spec.

Pinout & Package
TEA19051BAAT/1J is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads and 3.9 mm body width, optimized for high-density USB-PD charger designs requiring minimal external components.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Supply input | Secondary-side DC supply (up to 21 V); powers internal circuits and triggers UVLO/OVP/UVP based on programmed % of PDO |
| SW | NMOS gate driver | Charge-pump boosted output (VCC + 6 V) directly drives external load switch; ensures safe power path control |
| OPTO | Optocoupler driver | Replaces TL431 cathode; interfaces with primary-side controller (e.g., TEA193x) via single optocoupler for CV/CC feedback |
| GND | Power ground | Main return path for internal digital/analog blocks; separate from SGND to avoid noise coupling in current sensing |
| SGND | Sense ground | Dedicated low-noise ground for ISNS and VSNS; must be connected via independent trace to sense resistor ground |
| DISCH | Fast Vbus discharge sink | Internal low-RON switch discharges output to <0.8 V for USB-PD hard reset; includes millisecond-gated sampling for vSafe0V verification |

| ISNS | Current sense input | Accepts mV-level drop across external sense resistor (2–22 mΩ); 50× internal gain ensures sub-2.5 V compliance |
| VSNS | Voltage sense input | Monitors scaled-down Vout via MTP-matched resistor divider; sets CV reference with 12-bit DAC precision |
| CC1 / CC2 | USB-C configuration channel | Hardware-based attach/detach detection and USB-PD physical layer (PHY); supports Rp/Rd pull-up/pull-down per USB-C v1.3 |
| DP / DM | QC/BC data interface | Enables Qualcomm QuickCharge 2.0/3.0/4+ negotiation and BC1.2 D+/D− handshake; must be shorted for BC1.2 compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-PD secondary-side controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | USB-PD 3.0 sink-only controller; lacks QC support, CC mode, and integrated SW driver; requires external MCU for full DFP functionality | Targeted at cost-sensitive USB-C accessories where QC compatibility is not required; no PPS or multi-protocol negotiation | Choose STUSB4500QTR only for pure USB-PD sink applications with minimal feature set and lower power density requirements. |
| MPQ4282-AEC1 | Automotive-grade USB-PD 3.0 controller with AEC-Q100 qualification; includes CAN interface but no QC support or MTP-configurable PDOs | Designed for vehicle-mounted chargers requiring automotive reliability; lacks consumer-focused features like BC1.2 or DP/DM QC pins | Select MPQ4282-AEC1 exclusively for automotive infotainment or telematics power systems needing AEC-Q100 compliance and CAN integration. |
Compared with TEA19051BAAT/1J, STUSB4500QTR offers simpler USB-PD sink functionality but no QC or PPS, while MPQ4282-AEC1 adds automotive qualification and CAN at the expense of consumer protocol flexibility and field-programmable PDOs - making TEA19051BAAT/1J the only option supporting full USB-PD 3.0 + QC4+ + BC1.2 in a single SO14 package with hardware-enforced safety.

FAQ
What protocols does the TEA19051BAAT/1J support natively?
The TEA19051BAAT/1J natively supports USB Power Delivery 2.0 and 3.0 (including Programmable Power Supply), Qualcomm QuickCharge 2.0/3.0/4+, Battery Charging 1.2, and USB Type-C v1.3. All protocol stacks are implemented in firmware with hardware-accelerated PHY layers on CC1/CC2 and DP/DM pins - no external MCU is required for basic operation of TEA19051BAAT/1J.
How many Power Data Objects (PDOs) can be stored in the TEA19051BAAT/1J MTP memory?
The TEA19051BAAT/1J supports up to seven Power Data Objects stored in its non-volatile Multi-Time Programmable (MTP) memory. Four of these can be configured as Programmable Power Supply (PPS) objects, while the remaining three may be set as fixed PDOs. Each PDO includes independent settings for voltage, current, OCP/CC mode, and cable compensation enablement - all configurable during manufacturing or field programming of TEA19051BAAT/1J.
Does the TEA19051BAAT/1J require an external microcontroller to operate?
No, the TEA19051BAAT/1J does not require an external microcontroller. It integrates an embedded MCU with ROM, RAM, and MTP memory, along with dedicated hardware blocks for USB-PD PHY, QC protocol handling, CV/CC regulation, and protection logic. The TEA19051BAAT/1J operates autonomously as a complete secondary-side controller - only external passive components (resistors, NTCs, sense resistor, optocoupler) and an NMOS load switch are needed for full USB-PD 3.0 + QC4+ functionality.
What is the purpose of the DISCH pin on the TEA19051BAAT/1J?
The DISCH pin on the TEA19051BAAT/1J provides hardware-controlled fast discharge of the Vbus output to meet USB-PD vSafe0V requirements (<0.8 V) during hard resets. It contains an internal low-RON switch that sinks current through an external series resistor. To verify discharge completion, the TEA19051BAAT/1J periodically opens the DISCH switch for 20 µs every millisecond while monitoring actual Vbus voltage - ensuring reliable compliance with USB-PD specification timing and safety thresholds.
Can the TEA19051BAAT/1J be used in both USB-C and USB-A charger designs?
Yes, the TEA19051BAAT/1J supports both USB-C and USB-A topologies. In USB-C designs, CC1/CC2 pins handle plug detection and USB-PD communication. In USB-A configurations, attach/detach detection can be disabled via MTP programming, and the load switch remains closed unless triggered by protection events. DP/DM pins retain full QC2.0/3.0/4+ and BC1.2 functionality regardless of connector type - enabling flexible reuse of TEA19051BAAT/1J across multiple product lines.
