USB PD3.0 and QC4.0 Type-C Controller for SMPS

The TEA19032BT is a highly configurable secondary side SMPS controller that is available 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^® QuickCharge^TM QC4.0

A complete smart-charging Switch Mode Power Supply (SMPS) can be built in combination with the TEA193x primary controller and the TEA199x secondary side Synchronous Rectifier (SR) controller.

The TEA19032BT 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 TEA19032BT has a high level of digital integration. It incorporates all required circuits, including a charge pump to drive an external NMOS load switch directly, a USBPD physical interface (PHY), and an integrated driver for fast output discharge.

The output voltage and output current are continuously measured and are used to control the SMPS. The GPIO pin measures the adapter temperature or the temperature in the cable/connector. Optionally, the GPIO pin can be used for other features. The die temperature of the TEA19032BT is monitored via an internal temperature sensor.

Multiple protections ensure the robust charging safety for the TEA19032BT. To ensure correct operation under all conditions, all protections except UVP are implemented in hardware.

For output voltage regulation, current regulation and protection, only a single optocoupler 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.
