TSL2521 − 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 7:

Recommended Operating Conditions

Note(s):

1. While the device is operational across the temperature range, functionality will vary with temperature.

Figure 8:

Electrical Characteristics of TSL2521, VDD = 1.8 V, TA = 25°C (unless otherwise noted)

Note(s):

1. This parameter indicates the supply current during periods of ALS integration. The ALS gain setting will have an effect on the active

supply current. The ALS gain setting used for this parameter is 128x and there are 2 modulators active.

2. Idle state occurs when PON=1 and all functions are disabled. This parameter is measured with LOWPOWER_IDLE=1.

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.
