描述 Description

The TEA19032BT is a highly configurable secondary side SMPS controller that isavailable in many factory configured versions.
The TEA19032BT is a secondary side SMPS controller that supports the following protocols:
USB Type-C v.1.3
USB PD3.0 /PPS
Qualcomm® QuickChargeTM QC4.0
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 TEA19032BT can be provided in several small packages with low pin count. Dueto its small number of external components, a small form factor SMPS can be built thatmeets efficiency requirements like CoC Tier-2, EuP Iot6, and DOE v6 with an extremelyno-load power (< 30 mW).
The TEA19032BT 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.
The output voltage and output current are continuously measured and are used to controlthe SMPS. The GPIO pin measures the adapter temperature or the temperature in thecable/connector. Optionally, the GPIO pin can be used for other features.The die temperature of the TEA19032BT is monitored via an internaltemperature sensor.
Multiple protections ensure the best-in-class charging safety for the TEA19032BT.To ensure correct operation under all conditions, all protections except UVP areimplemented in hardware.
For output voltage regulation, current regulation, and protection, only a singleoptocoupler is required in the application.The TEA19032BT operates in CV mode with a better than 2 % voltage accuracy. In CC mode, it operates with a better than 2 % full-load current accuracy.
