The bq51025 device integrates an ultra-low-impedance synchronous rectifier, a very-high-efficiency post regulator, digital control, and accurate voltage and current loops. The bq51025 devices provide the AC/DC power conversion while integrating the digital control required. The IC complies with the WPC v1.1 communication protocol. Together with a bq500xxx primary-side controller transmitter (or any other WPC v1.1 transmitter), the bq51025 enables a complete contactless power transfer system for a 5-W wireless power supply solution. By utilizing near-field inductive power transfer, the secondary coil embedded in the mobile device can pick up the power transmitted by the primary coil. The voltage from the secondary coil is then rectified and regulated to be used as a power supply for down-system electronics. Global feedback is established from the secondary to the primary in order to control the power transfer process. In WPC, system communication is digital (packets are transferred from the secondary to the primary). Differential bi-phase encoding is used for the packets. The bit rate is 2 kb/s. Various types of communication packets have been defined. These include identification and authentication packets, error packets, control packets, power usage packets and efficiency packets, among others. When paired with the bq500215 primary-side controller transmitter, the bq51025 is capable of delivering up to 10 W. The bq51025 incorporates a proprietary two-way authentication with the bq500215 primary controller that allows optimal power transfer and system performance up to 10-W output power. 2 bq51025 Evaluation Module (PWR649) SLUUB55 – September 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Considerations with this EVM www.ti.com 2 Considerations with this EVM The bq51025EVM-649 evaluation module (PWR649) demonstrates the receiver portion of the wireless power system. This receiver EVM is a complete receiver-side solution that produces 10-W output power at up to 2-A load with adjustable output voltage. The 10-W output power can be delivered from various output voltages. The output current is limited so that the overall delivered power is less than 10 W. For example, a 10-V output can supply up to 1 A, whereas a 5-V output can deliver up to 2 A. The default configuration for this EVM is a 7-V output capable of delivering up to 1.43 A. • The receiver can be used in any number of devices as a power supply for a battery charger. With contact-free charging capability, no connections to the charging power source are required. • 5-W power delivery with any WPC v1.1 transmitter • 10-W power delivery with the bq500215 transmitter • Highly-integrated wireless power receiver solution – Ultra-efficient synchronous rectifier – Very high efficiency post regulator – WPC v1.1-compliant communication and control – Only one IC required between RX coil and DC output • Programmable output voltage to optimize performance for application • Adaptive communication current limit (CM_ ILIM) for robust communication • Supports 20-V max input • Low-power dissipative overvoltage clamp • Overvoltage, overcurrent, overtemperature protection • Low-profile, external pick-up coil • Frame is configured to provide correct receiver to transmitter spacing • Room above coil for testing with battery, key for Foreign Object Detection (FOD) tuning • Options to adjust the input current limit and output voltage using resistors or I2C • Flexibility for FOD tuning • Adjustable resistor that can be used to set RFOD • Temperature sensing can be adjusted using external resistors • Micro-USB connector for adapter testing configuration • I2C connector (USB-TO-GPIO "HPA172" kit for I2C communication through computer is required) • WPG LED indicator (Green LED is on when VOUT is high) • PD_DET LED indicator (Orange LED is on when the RX is on TX pad) SLUUB55 – September 2014 Submit Documentation Feedback bq51025 Evaluation Module (PWR649) Copyright © 2014, Texas Instruments Incorporated 3 Modifications 3 www.ti.com Modifications See the bq51025 data sheet (SLUSBX7) when changing components. To aid in such customization of the EVM, the board was designed with devices having 0402 and 0603 or larger footprints. A real implementation likely occupies less total board space. Note that changing components can improve or degrade EVM performance. Special attention should be given to the resonant capacitors (C1, C2, and C3). Thermal performance of these capacitors can greatly impact overall system performance. 4 Recommended Operating Conditions Table 1 provides a summary of the bq51025EVM-649 performance specifications.

Otherwise, this may cause the voltage to drop and could cause thermal issues. • Keep the trace resistance as low as possible on AC1, AC2, OUT, and PGND • Use the appropriate current rating traces (width) on AC1, AC2, OUT, and PGND • The PCB should have a ground plane (return) connected directly to the return of all components through vias (At least two vias per capacitor for power-stage capacitors, one via per capacitor for small-signal components). • Dissipation of heat is very important. The layout must allow for transfer of heat from high power items. Adding internal layers increases the thermal performance. Multiple vias in the PGND pins of the IC is recommended to decrease the thermal resistance in the board and allow much easier thermal dissipation through inner layer and power ground layers. • The via interconnect is important and must be optimized near the power pad of the device and ground • 2-oz copper, or greater, is recommended • For high-current applications, the balls for the power traces should be connected to as much copper in the board as possible. This allows better thermal performance because the board conducts heat away from the device. • It is always good practice to place high frequency bypass capacitors next to RECT and OUT 8.3 Printed-Circuit Board Layout Example The primary concerns when laying a custom receiver PCB are as follows: • AC1 and AC2, GND return trace resistance • OUT trace resistance • GND connection • Copper weight ≥ 2 oz SLUUB55 – September 2014 Submit Documentation Feedback bq51025 Evaluation Module (PWR649) Copyright © 2014, Texas Instruments Incorporated 19 Layout and Bill of Material www.ti.com For a 1.4-A fast charge current application, the current rating for each net is as follows: • AC1 = AC2 = 2.2 A • BOOT1 = BOOT2 = 1 A • RECT = 200 mA (RMS) • OUT = 2.5 A • COMM1 = COMM2 = 600 mA • CLAMP1 = CLAMP2 = 1000 mA • ILIM = 10 mA • AD = AD_EN = TS/CTRL = FOD = 1 mA TI also recommends having the following capacitance on RECT and OUT: • RECT ≥ 22 μF • OUT ≥ 1 μF It is always good practice to place high-frequency bypass capacitors next to RECT and OUT of 0.1 μF. Figure 11 illustrates an example of a WCSP layout. OUT AD Keep the trace resistance as low as possible on AC1, AC2 and OUT GND AD trace to wired power bypass FET is a power path GND Isolate noisy traces using GND path R CO R CP AC1 B D GND RECT D R Signal and sensing components should be placed as close to the device as possible B CP COMM, CLAMP and AC2 BOOT capacitors are CO GND High frequency bypass capacitors should be placed close to RECT and OUT Detection and Resonant capacitors should be placed as close to the device as possible placed as close to the device as possible bq51025YFP Via interconnects are used to aid in thermal dissipation t use where possible Figure 11. bq51025EVM-649 Layout Example 20 bq51025 Evaluation Module (PWR649) SLUUB55 – September 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Layout and Bill of Material www.ti.com 8.4 bq51025EVM-649 Layout Figure 12 through Figure 16 show the bq51025EVM-649 PCB layout.
