The TEA19051BAAT/1J supports the following protocols:
- USB Type-C v.1.3
- USB Power Delivery (USB-PD) including Programmable Power Supply (PPS)
- Battery Charging 1.2 (BC1.2)
- Qualcomm® QuickCharge™ QC2.0, QC3.0, and QC4+
A complete smart-charging Switch Mode Power Supply (SMPS) can be built incombination with the TEA193x primary controller and the TEA199x secondary sideSynchronous Rectifier (SR) controller.
The TEA19051BAAT/1J can be provided in several small packages with low pin count. Due to its small number of external components, a small form factor SMPS can be built that meets efficiency requirements like CoC Tier-2, EuP Iot6, and DOE v6 with an extremely no-load power (< 30 mW).
The TEA19051BAAT/1J has a high level of digital integration. It incorporates all requiredcircuits, including a charge pump to drive an external NMOS load switch directly,a USBPDphysical interface (PHY), and an integrated driver for fast output discharge.
