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 a bqTESLA™ receiver. The EVM requires only input power for operation, 12 V at 1 A or 5 V at 2.5 A. All transmitter-side electronics and transmitter coils are on a single 4-layer printed-circuit board (PCB). The open design allows easy access to key points of the electrical schematic.

  • WPC A6-Type transmitter coil, 70 mm × 25 mm free positioning area
  • Input voltage 12 V or 5 V, using optional boost converter
  • 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 (for example, 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
