3. Occurs once during powerup. Duration is <5 msec.
4. Occurs during I2C commands for Reset, Read/Write User Registers, Read EID, Read Firmware Version, Read/Write
Thermistor Coefficients and Measure Analog Voltage or Thermistor Temperature. Duration is <50 μs for all commands
except Measure Analog Voltage or Thermistor Temperature, which has <150 μs duration when Thermistor Correction is
enabled.
5. IDD after a user register write. Initiating any other subsequent I2C transaction on the same bus (such as a user register
read, starting an RH measurement, or traffic directed at other I2C devices) will transition the device to standby mode.
6. Additional current consumption when HTRE bit enabled. See Section “5.6. Heater” for more information.
