TEA19051BT USB-PD 2.0/USB-PD 3.0/QC 2.0/QC 3.0/QC 4 (+) controller for SMPS Rev. 1 13 February 2018 Product data sheet 1 General description The TEA19051BT is a highly configurable secondary side SMPS controller that is available in many factory configured versions. Section 15 gives an overview of the available off-the-shelf versions of the TEA19051BT. To inquire about the possibilities of customer-specific versions, contact your local sales representative. The TEA19051BT 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 in combination with the TEA193x primary controller and the TEA199x secondary side Synchronous Rectifier (SR) controller. The TEA19051BT 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 TEA19051BT 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 USB- PD 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. Two GPIO pins measure the adapter temperature and the temperature in the cable/connector. Optionally, the GPIO pins can be used for other features, like supply (see Table 4). The die temperature of the TEA19051BT is monitored via an internal temperature sensor. Multiple protections ensure the best-in-class charging safety for the TEA19051BT. To ensure correct operation under all conditions, all protections except UVP are implemented in hardware. The response of these protections can be programmed as latched or safe restart. Although not recommended, these protections can also be disabled individually via the settings in the non-volatile Multi-Time Programmable (MTP) memory. If an output short circuit occurs, the power dissipation in the adapter can be below 50 mW. For output voltage regulation, current regulation, and protection, only a single optocoupler is required in the application. The TEA19051BT 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.NXP Semiconductors TEA19051BT USB-PD 2.0/USB-PD 3.0/QC 2.0/QC 3.0/QC 4 (+) controller for SMPS 2 Features and benefits 2.1 General Best-in-class fail-safe application for high-power adapters gives complete protection against overload conditions in the load (e.g. phone) Wide output voltage operating range (2.9 V to 21 V) Ultra-high efficiency together with TEA193x QR/DCM controller and TEA199x SR controller Very low no-load power (< 30 mW for the complete system solution) High power density Dedicated SW pin to drive external NMOS directly Constant Voltage (CV) and Constant Current (CC) control (programmable level) Precise voltage and current control with low minimum step size (voltage 12-bit DAC, current 10-bit DAC) Continuous accurate measurement of output voltage and output current with a better than 2 % accuracy Low-cost SO14 package (suitable for reflow soldering and wave soldering) Low-cost Bill Of Materials (BOM 15 external components) Embedded MCU (with ROM, RAM, and MTP memory) Discharge pin for fast output voltage ramp down Built-in series regulator and programmable cable compensation Non-volatile MTP memory for storage of system configuration parameters 2.2 Protocol support USB Type-C v.1.3 USB Power Delivery (USB-PD) 2.0 and 3.0 including Programmable Power Supply (PPS) Supports Qualcomm QuickCharge QC2.0, QC3.0, and QC4+ protocols Battery Charging 1.2 (BC 1.2) Supports unstructured Vendor Defined Messages (VDMs), which can be used for MTP programming, e.g. to get Vendor IDs TEA19051BT All information provided in this document is subject to legal disclaimers.
