49 / 60 page  Power= Current BusVoltage ´ 5000 TPS2480 TPS2481 www.ti.com SLUS939B – APRIL 2010 – REVISED DECEMBER 2010 Bus Voltage Register 02h (Read-Only) The Bus Voltage Register stores the most recent bus voltage reading, VBUS. At full-scale range = 32 V (decimal = 8000, hex = 1F40), and LSB = 4 mV. BIT # D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 BIT BD12 BD11 BD10 BD9 BD8 BD7 BD6 BD5 BD4 BD3 BD2 BD1 BD0 — CNVR OVF NAME POR 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 VALUE At full-scale range = 16 V (decimal = 4000, hex = 0FA0), and LSB = 4 mV. BIT # D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 BIT 0 BD11 BD10 BD9 BD8 BD7 BD6 BD5 BD4 BD3 BD2 BD1 BD0 — CNVR OVF NAME POR 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 VALUE CNVR: Conversion Ready Bit 1 Although the data from the last conversion can be read at any time, the TPS2480/81 Conversion Ready bit (CNVR) indicates when data from a conversion is available in the data output registers. The CNVR bit is set after all conversions, averaging, and multiplications are complete. CNVR will clear under the following conditions: 1) Writing a new mode into the Operating Mode bits in the Configuration Register (except for Power-Down or Disable) 2.) Reading the Power Register OVF: Math Overflow Flag Bit 0 The Math Overflow Flag (OVF) is set when the Power or Current calculations are out of range. It indicates that current and power data may be meaningless. Power Register 03h (Read-Only) Full-scale range and LSB are set by the Calibration Register. See the TPS2480/81 Power Measurement Engine section. BIT # D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0 BIT PD15 PD14 PD13 PD12 PD11 PD10 PD9 PD8 PD7 PD6 PD5 PD4 PD3 PD2 PD1 PD0 NAME POR 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 VALUE The Power Register records power in watts by multiplying the values of the current with the value of the bus voltage according to the equation: Copyright © 2010, Texas Instruments Incorporated Submit Documentation Feedback 49 Product Folder Link(s): TPS2480 TPS2481 |
