bq500215 WPC v1.1 Compliant Wireless Power Transmitter Manager With Proprietary 10-W Power Delivery

Overview

TopologyBuck Converter
Input voltage11.5-12.5 V
Output 17 V / 1.4 A
IC revisionA

Description

The bq500215 is a dedicated wireless power digital controller that integrates the logic functions required to control wireless power transfer to a single WPC-compliant receiver. The bq500215 complies with the WPC v1.1 standard for power delivery up to 5 W and uses a proprietary bidirectional communication protocol to allow charging at up to 10 W with the bq51025 wireless power receiver. The bq500215 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 bq500215 also manages the fault conditions associated with the power transfer and controls the operating mode status indicator. The bq500215 uses a rail voltage control scheme instead of the traditional frequency control to adjust the amount of power delivered to the receiver.
