Description
The TS81001 is a power receiver communications and control
unit for wireless charging applications. The TS81001 can
support systems up to 40W+, and supports Qi® compliant,
PMA compliant and proprietary applications.
The TS81001 performs the necessary coding of packets to
send commands to the transmitter to adjust the power level
accordingly.
Specification
• RISC-based controller core with flash and SRAM memory
• 12-bit A/D converter
• Two 16-bit timers
• 8-bit timer
• Auto-wakeup and watchdog timers
• 8 configurable analog general purpose IOs
• Charging LED output
• I2C interface
• 20 pin 3x3 QFN

Notes:
(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings
only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating condi-
tions” is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground terminal.
(3) ESD testing is performed according to the respective JESD22 JEDEC standard.

Communication Interfaces
I2C or UART communication can only take place in the following cases:
The Wireless Power Receiver is placed on the Wireless Power Transmitter and power transfer is taking place, or
External power is applied, either through the system power supply or on the TS51111 USB pin
In both cases, an internal voltage regulator inside the TS51111 provides 3.3V on the VCORE pin for the TS81001 to use.
The Applications Processor can interrogate the TS81001 using the I2C or UART interfaces. The TS81001 acknowledges its I2C Slave
Address only if it is powered. No ACK from the TS81001 after its slave address means that power transfer does not take place and
power is not applied to the TS51111 USB pin.
