Page 18: Pmbus Interface
TPS4000 SERIES POWER SUPPLY OPERATION MANUAL PMBus Interface The TPS4000 has Power Management Bus (PMBus) hardware. The PMBUS interface in the TPS4000 includes: • Monitoring the Output Voltage (+/- 2% of Full Scale). • Monitoring the Output Current (+/- 10% of Full Scale). - Page 19 TPS4000 SERIES POWER SUPPLY OPERATION MANUAL ADDRESSING (A3, A2, A1, A0 inputs) To communicate with the TPS4000, the master must first address the slave devices via a slave address byte. The slave address byte consists of seven address bits and a direction bit that indicates the intent to execute a read or write operation.

- Page 22 TPS4000 SERIES POWER SUPPLY OPERATION MANUAL READ_STATUS This Command is used to read the status of the Power Supply. The Status information is stored in a special register called the “STATUS REGISTER”. The PMBus reads 16 different types of Faults and Warnings.
- Page 23 TPS4000 SERIES POWER SUPPLY OPERATION MANUAL WARNING Invalid Command Received Output ON PROGRAMMING AND MONITORING FUNCTIONS For Monitoring and Programming functions use the following equation Y = (mX + b)* 10 X = (Y*10 - b)/m Where: Y is the digital value sent or received from the supply.
- Page 24 TPS4000 SERIES POWER SUPPLY OPERATION MANUAL MONITORING THE OUTPUT VOLTAGE (READ_VOUT) The accuracy of the voltage reading is +/-2% The output voltage is read before the ORING Circuit (~50mV Voltage drop @ load, no drop @no load). The read back Output Voltage can be calculated using the “Direct data Format”.
- Page 25 TPS4000 SERIES POWER SUPPLY OPERATION MANUAL PROGRAMMING THE OUTPUT VOLTAGE (VOUT_COMMAND) The accuracy of the Output Voltage Programming is +/-2% The output Voltage can be programmed using the “Direct data Format”. Please refer to table 1 for the Coefficients to be used for calculating the Voltage Programming.
