Note 1: Specifications to -40 ° C are guaranteed by design and not production tested.
Note 2: LED current matching is defined as: (I LED - I AVG ) / I AVG
Note 3: Dropout voltage is defined as the LED_-to-GND voltage at which current into the LED drops 10% from the LED current at
V LED_ = 0.2V.
Typical Operating Characteristics
(V IN = 3.6V, ENM = ENS = IN, circuit of Figure 2, T A = +25 ° C, unless otherwise noted.)
