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. 1 • • • • • • • • Qi-Certified Wireless Power Consortium (WPC) v1.2 Solution for 15-W Operation – Faster Charging Time – Backward Compatible With Existing 5-W WPC Receivers 12-V to 19-V Input, Fixed Frequency, Rail Voltage Control Architecture – 15 V to 19 V can achieve 15 W – 9 V and 12 V capable for HVDCP – Dynamic Power Limiting (DPL) Allows Operation From Weak Supplies Conforms to WPC MP-A5 Transmitter Type Specification Enhanced Foreign Objection Detection (FOD) Implementation With FOD Ping that Detects Metal Objects Prior to Power Transfer Low Standby Power During Idle and 'Charge Complete' Bi-directional Communication Digital Demodulation Reduces Components and Simplifies Circuitry Support Fast Charge Operation with Compatible Receivers 10 Configurable LED Modes Indicate Charging State and Fault Status WPC v1.2 Wireless Chargers: – Smart Phones, Tablets, and Other Handhelds – Point-of-Sale Devices – Custom Wireless Power Applications space Transmitter Solution Simplified Diagram 19-V Supply Fast Charge support provides more power for compatible receiver devices. See www.ti.com/wirelesspower for more information on TI's Wireless Charging Solutions Device Information(1) PART NUMBER 2 Applications • 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.
