TSL2541 − 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. Specifications are stated at

25°C unless otherwise noted.

Figure 7:

Operating Characteristics, VDD = 1.8V, TA = 25°C

Note(s):

1. This parameter indicates the supply current during periods of ALS integration. If Wait is enabled (WEN=1), the supply current is

lower during the Wait period.

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

3. 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.

4. Digital pins: SDA, SCL, INT, are tolerant to a communication voltage up to 3.0V.
