BQ500412EVM-584 Applications

The bq500412EVM-584 evaluation module demonstrates the transmitter portion of the bqTESLA™wireless power system. This transmitter EVM is a complete transmitter-side solution that powers abqTESLA™ receiver. The EVM requires only input power for operation, 12 V at 1 A or 5 V at 2.5 A. Alltransmitter-side electronics and transmitter coils are on a single 4-layer printed-circuit board (PCB). Theopen design allows easy access to key points of the electrical schematic.This EVM has the following features: • WPC A6-Type transmitter coil, 70 mm × 25 mm free positioning area • • WPC 1.1 Foreign Object Detection (FOD) and WPC 1.0 Parasitic Metal Object Detection (PMOD) • Dynamic Power Limiting™ (DPL) allows operation from a 5-V supply with limited current capability (forInput voltage 12 V or 5 V, using optional boost converterexample, a USB port) • Reduced parts count from the legacy bq500410A design • Compact power section design using the CSD97374 NexFET power stage •LED indicates power transfer or power fault state
