These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” 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.

The TS80002 acknowledges its I2C Slave Address only if it is powered. No ACK from the TS80002 after its slave address means that power is not applied to the TS80002.
www.semtech.com 6 of 16 SemtechRev.1.2 I2C I2C Signal Pins ALERT pin (GPIO pin) - optional: Driven high when an event is active in the internal STATUS register Driven low when all the internal events are cleared Note: The ALERT pin is provided to help with I2C communication, i.e. to signal events to the EC so the EC can interrogate the TS80002 via I2C. The use of the ALERT pin is not mandatory in the application. SCL pin: Clock pin for the I2C interface. True open-drain. Needs external pull-ups. SDA pin: Data pin for the I2C interface. True open-drain. Needs external pull-ups. I2C Protocol The TS80002 Wireless Power Receiver acts as an I2C slave peripheral to allow communication with an application microcontroller. The slave address (7 bit) is 0x49. The Embedded Controller is an I2C master and initiates every data transfer. The TS80002 implements a set of registers available from the I2C bus. It also implements a set of API functions that receive parameters and return values using the I2C bus. Four transfer types are possible: Write Register Read Register Run API Function Read API Function Return Buffer Write Register Operations Description START Start of the I2C transfer. M→S Slave Address (7 bits) 0 (1 bit) Slave ACK Slave address + R/W bit (0x92 as 8-bit). M→S Register n address (8 bits) Slave ACK Address of the first register. M→S Register n Data (8 bits) Slave ACK Write the first register. M→S Register n+1 Data (8 bits) Slave ACK Optionally write the following registers. ... M→S Register n+k Data (8 bits) Slave ACK STOP Stop of the I2C transfer. Read Register Operations Description
www.semtech.com 7 of 16 SemtechRev.1.2 START Start of the I2C transfer. M→S Slave Address (7 bits) 0 (1 bit) Slave ACK Slave address + 0 as R/W bit (0x92 as 8-bit). M→S Register n address (8 bits) Slave ACK Address of the first register. START Repeated Start. M→S Slave Address (7 bits) 1 (1 bit) Slave ACK Slave address + 1 as R/W bit (0x93 as 8-bit). S→M Register n Data (8 bits) Master ACK Read the first register. S→M Register n+1 Data (8 bits) Master ACK Optionally read the following registers. ... S→M Register n+k Data (8 bits) Master nACK The master should send a nACK after the last data byte was received. STOP Stop of the I2C transfer Run API Function Description Start Start of the I2C transfer. M→S Slave Address (7 bits) 0 (1 bit) Slave ACK Slave address + R/W bit (0x92 as 8-bit). M→S API number (8 bits) Slave ACK API number. M→S API input buffer length m (8 bits) Slave ACK API input buffer length. Equal to 0 if no input buffer data is required by the API. M→S Input buffer data[0] (8 bits) Slave ACK First byte of the input buffer (optional). M→S Input buffer data[1] (8 bits) Slave ACK Second byte of the input buffer (optional). ... M→S Input buffer data[m-1] (8 bits) Slave ACK Last byte of the input buffer (optional). Stop Stop of the I2C transfer and execute the API function. Read API Function Return Buffer Description START Start of the I2C transfer. M→S Slave Address (7 bits) 0 (1 bit) Slave ACK Slave address + 0 as R/W bit (0x92 as 8-bit).
