TI公司的bq501210是符合无线充电同盟(WPC) v1.2尺度的无线电源数字控制器,集成了符合WPC的吸收器无线传输功率所需的逻辑功能,最高能够传输15W功率,12V至19V输入,具有双向通信,支持对兼容吸收器举行快速充电,可选择提供5W WPC低功率或15W中等功率,主要用在WPCv1.2无线充电器如Qi认证智能手机,平板电脑和其它手持设备,销售点设备和定制无线电源.本文先容了bq501210主要特点,功能框架图,系统框架图以及评估板bq501210EVM-756主要特点,电路图和质料清单. The bq501210 is a Wireless Power Consortium (WPC) v1.2 compliant wireless power digital controller that integrates the logic functions required to wirelessly transfer power to a WPC-compliant receiver with the capability of delivering up to 15 W. The bq501210 is an intelligent device that periodically pings the surrounding environment for available devices to be powered, detects if a foreign metal object is present on the charging pad, monitors all communication from the device being wirelessly powered, and adjusts power applied to the transmitter coil per feedback received from the powered device. The bq501210 also manages the fault conditions associated with the power transfer and controls the operating mode status indicator. The bq501210 uses a rail voltage control scheme instead of the traditional frequency control to adjust the amount of power delivered to the receiver. Through negotiation with a High Voltage Dedicated Charging Port (HVDCP) adapter, the bq501210 provides power between the WPC low power capability of 5 W, and the medium power specifications of 15 W.Fast Charge support provides more power for compatible receiver devices. bq501210主要特点: Qi-Certified Wireless Power Consortium (WPC) v1.2 Solution for 15-W Operation bq501210应用: WPC v1.2 Wireless Chargers: 评估板bq501210EVM-756 The bq501210EVM-756 EVM demonstrates the transmitter portion of the bqTESLA™ wireless power system. This transmitter EVM is a complete transmitter-side solution that powers a bqTESLA receiver. The EVM requires a single 12-V power supply capable of up to 2.0A to operate and combines the transmitter electronics, input pwoer circuit, LED indicators, and the transmitting coil on the single printed-circuit board (PCB). The EVM is a non-space optimized, open design allowing easy access to key points of the electrical schematic. 评估板bq501210EVM-756主要特点: WPC v1.2 15-W charging capability with bq55221 receiver BQ501210EVM-756 bq501210 WPC 1.2 Wireless Power Transmitter Manager Evaluation Module with 15-W Power Delivery Board Image 评估板bq501210EVM-756电参数指标: |
