【文字介紹】

The TS80000 is a power transmitter communications and control unit for wireless charging applications. The TS80000 can support power outputs up to 40W+, and supports Qi® compliant, PMA compliant and proprietary applications. The TS80000 can be configured to drive single or multi-coil applications, in half and full-bridge systems. The TS80000 performs the necessary decode of packets from the secondary side device and adjusts the control accordingly. An integrated PID filter provides the necessary compensation for the loop for high-precision control of duty cycle, frequency, and or bridge voltage.
