ИС беспроводного зарядного устройства BQ51013ARHLT

Беспроводной приемник питания , протокол связи Qi v1.0, 2В до 10В, QFN-20

Integrated wireless power supply receiver with 5V regulated supply. The device provides AC/DC power conversion while integrating the digital control required to comply with Qi v1.0 communication protocol. Together with the bq500210 transmitter controller, this device enables a complete contact-less power transfer system for a wireless power supply solution. It 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. Typically used in cell phones, smart phones, headsets, digital cameras, portable media players and hand held devices.

• 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
• Supports 20V maximum input
• Low power dissipative rectifier overvoltage clamp (VOVP = 15V)
• Multifunction NTC and control pin
• Programmable termination pin
• Stand-alone digital controller
