Qi v1.3 EPP free position transmitter
REF_WLCAUTO_TX15W_C1 is a highly integrated Qi v1.3 EPP transmitter design. This reference board operates with an automotive battery input voltage between 9 V-18 V, supporting reverse polarity protection and auto transients. On-chip LIN or serial interfaces can be used to communicate with the host system for additional functionality. Additional features of AUTOSAR, CAN and NFC can be supported with an external MCU such as TRAVEO™ II or PSoC™.
Summary of Features
Supports BPP, PPDE and custom protocol
Input voltage 4.5–24 V (40 V tolerant)
Output power: 15 W Qi EPP free position
Integrated buck-boost controller
Integrated gate drivers
Slew rate and dithering controls
UVLO, OVP, OCP and OTP protections
LIN and host interface
In-built LIN interface
External LIN transceiver
Interface to external MCU over I2C
68 QFN (10x10 mm) automotive grade
Benefits
Scalable solution for in-cabin charging
Qi stack with library support
Fixed frequency operation for low EMI
Configurable gate drivers for EMC
Configurable FOD and protections
