TMD3725 − 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. The minimum required supply voltage on the LED anode (VLEDA) is the sum of the LED's VF and the voltage drop from the LDR pin

to PGND pin. The minimum required VLEDA can be lowered to 2.8V if the LED's forward current does not exceed 102mA (PLDRIVE

value of 16 or less).

2. 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, VDD = 1.8V, TA = 25°C (unless otherwise noted)

Note(s):

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

2. 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.

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.
