TMD3721 − Electrical Characteristics

All limits are guaranteed. The parameters with min and max

values are guaranteed with production tests or SQC (Statistical

Quality Control) methods.

Figure 6:

Recommended Operating Conditions

Note(s):

1. While the device is operational across the temperature range, performance will vary with temperature. Operational characteristics

are at 25°C, unless otherwise noted.

Figure 7:

Operating Characteristics, VDD18 = 1.8V, VDD3 = 3.0V, TA = 25°C (unless otherwise noted)

Note(s):

1. Values are shown at the VDD18 pin and do not include current through the IR VCSEL emitter.

2. Active state occurs when PON =1 and the device is actively integrating either proximity or ALS.

3. Idle state occurs when PON =1 and all functions are not enabled.

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.
