Product Overview

The BQ51013ARHLR is an integrated Receiver IC for wireless power transfer in portable applications. The device provides the AC/DC power conversion while integrating the digital control required to comply with the Qi v1.0 communication protocol. The AC signal from the receiver coil is then rectified and regulated to be used as a power supply for down-system electronics. Global feedback is established from the secondary to the transmitter in order to stabilize the power transfer process via back-scatter modulation. This feedback is established by using the Qi v1.0 communication protocol supporting up to 5W applications. The device integrates a low-impedance full synchronous rectifier, low-dropout regulator, digital control and accurate voltage and current loops. The entire power stage (rectifier and LDO) use low resistive NMOS FET's to ensures high efficiency and low power dissipation.
  • 93% Overall peak AC-DC efficiency
  • Full synchronous rectifier
  • WPC v1.0 compliant communication control
  • Output voltage conditioning
  • Dynamic rectifier control for improved load transient response
  • Dynamic efficiency scaling for optimized performance over any range of output power
  • Adaptive communication limit for robust communication during high levels of load current noise
  • Supports 20V maximum input
  • Low-power dissipative rectifier overvoltage clamp (VOVP = 15V)
  • Thermal shutdown
  • Multifunction NTC and control pin for temperature monitoring, done charging and fault host control
  • Stand-alone digital controller
  • Programmable termination pin for charge status 100% (CS100) support
