Product details
Overview
TEA19051BAPTK/1J from NXP Semiconductors is a USB-PD 3.0 and QC4+ secondary-side SMPS controller in HVSON16 package, delivering CV/CC regulation with <2% voltage accuracy and <2% full-load current accuracy, supporting programmable power supply (PPS), cable compensation, and hardware-enforced protections for high-power USB-C chargers.
For engineers reviewing the TEA19051BAPTK/1J datasheet, TEA19051BAPTK/1J pinout, TEA19051BAPTK/1J application, or TEA19051BAPTK/1J equivalent, key selection criteria include its integrated USB-PD PHY, dual CC/DP-DM protocol support, 16-pin HVSON package with SW and DISCH drive capability, and MTP-configurable PDOs up to 7 including PPS profiles.
Technical Context
The TEA19051BAPTK/1J implements a digitally enhanced analog control architecture: a 12-bit DAC sets output voltage via VSNS feedback, while a 10-bit DAC and 50× gain amplifier regulate current via ISNS sensing; all protections-including OVP, OTP (internal + two external), OSP, and soft-short detection on CC1/CC2-are implemented in dedicated hardware logic independent of firmware execution.
It integrates a charge pump driving the SW pin (VCC + 6 V) for direct NMOS gate control, a fast-discharge sink on DISCH with vSafe0V monitoring, and adaptive current sourcing on GPIO1/GPIO2 for NTC-based temperature measurement with <5 °C accuracy across 0–120 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-PD and QC secondary-side controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STUSB4500QTR | Standalone USB-PD 3.0 sink controller; lacks integrated CC/CV regulation, PPS, or NMOS gate drive | Requires external voltage/current controller and load switch; suitable only for sink-side applications | Choose STUSB4500QTR only when implementing a USB-PD sink-not a source/charger controller like TEA19051BAPTK/1J |
| MPQ4282-AEC1 | Automotive-grade USB-PD 3.0 source controller; includes integrated buck converter but no QC/BC1.2 support | Designed for vehicle infotainment power delivery; not qualified for consumer AC-DC adapter use | MPQ4282-AEC1 fits automotive environments but cannot replace TEA19051BAPTK/1J in universal fast-charge adapters due to missing QC protocols and non-reflow HVSON package |
Compared with STUSB4500QTR and MPQ4282-AEC1, the TEA19051BAPTK/1J uniquely combines USB-PD 3.0 PPS, QC4+, BC1.2, and hardware-enforced CV/CC regulation in a single HVSON16 device-eliminating external DACs, op-amps, and protection ICs required by alternatives.

FAQ
What USB-PD and QC protocols does the TEA19051BAPTK/1J support?
The TEA19051BAPTK/1J supports USB-PD 2.0 and 3.0-including Programmable Power Supply (PPS)-as well as Qualcomm QuickCharge QC2.0, QC3.0, and QC4+. It also implements Battery Charging 1.2 (BC1.2) and USB Type-C v1.3 physical layer requirements. All protocol handling is performed in hardware-assisted firmware with MTP-configurable PDOs.
How does the TEA19051BAPTK/1J achieve <2% voltage and current accuracy?
The TEA19051BAPTK/1J achieves better than ±2% voltage accuracy in CV mode using a 12-bit DAC referenced to an internal bandgap, and better than ±2% full-load current accuracy in CC mode via a 10-bit DAC driving a precision 50× current-sense amplifier on the ISNS pin. Both loops operate continuously with hardware-based ADC sampling and digital filtering initialized in firmware.
What protections are implemented in hardware versus firmware on the TEA19051BAPTK/1J?
All critical protections-including overvoltage (OVP), overtemperature (OTP) on die and two external sensors, output short (OSP), undervoltage (UVP), and soft-short detection on CC1/CC2-are implemented in dedicated hardware logic. Only non-safety-critical features like I²C configuration or VDM responses rely on the embedded MCU; hardware protections remain fully active even if firmware stalls.
Can the TEA19051BAPTK/1J drive an external NMOS load switch directly?
Yes, the TEA19051BAPTK/1J includes an integrated charge pump that boosts the SW pin output to VCC + 6 V, enabling direct gate drive of standard NMOS load switches without external level shifters. The SW pin is held low during UVLO or open-VCC conditions, ensuring fail-safe turn-off of the load switch under fault conditions.
What is the role of the DISCH pin on the TEA19051BAPTK/1J?
The DISCH pin on the TEA19051BAPTK/1J provides a low-ohmic internal switch to rapidly discharge the Vbus output to vSafe0V (<0.8 V) during USB-PD hard resets. It operates with millisecond-scale periodic sampling to verify final voltage drop while limiting peak current via an external series resistor-ensuring strict compliance with USB-PD vSafe0V timing requirements.
