TMG3992 − Electrical Characteristics

Note(s):

1. Values are shown at the VDD pin and do not include current through the IR LED.

2. Current consumption during an LDR pulse is referenced as “IDEVICE ANALOG” later in this document when calculating average power

consumption.

3. Current consumption by the device during sleep is also used to approximate “IDEVICE DRIVE” referenced later in this document when

calculating average power consumption.

4. Sleep state occurs when PON = 0 and I2C bus is idle. If Sleep state has been entered as the result of operational flow, SAI = 1, PON

will remain high.

Optical Characteristics (RGBC), VDD = 3V, TA = 25ºC

Note(s):

1. The 465nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics: dominant wavelength

λD = 465nm, spectral halfwidth Δλ½ = 22nm.

2. The 525nm input irradiance is supplied by an InGaN light-emitting diode with the following characteristics: dominant wavelength

λD = 525nm, spectral halfwidth Δλ½ = 35nm.

3. The 615nm input irradiance is supplied by a AlInGaP light-emitting diode with the following characteristics: dominant wavelength

λD = 615nm, spectral halfwidth Δλ½ = 15nm.
