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.

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.
