Enable Input/Power Input. Drive high (> 2.5V) to enable; drive low (< 2.2V) to
disable. When disabled, SET, LED1, LED2, LED3 and LED4 are high impedance.
When enabled, EN is the power input for the T6311A.
Ground
Bias Current Set Input. The current flowing into SET sets the bias current into each
LED by ILED_= 240 x ISET. VSET is internally biased to 1.2V. SET is high
impedance when EN is low.
No connection.
LED 4 Cathode Connection. Current flowing into LED4 is 240 times the current
flowing into SET. LED4 is high impedance when EN is low.
LED 3 Cathode Connection. Current flowing into LED3 is 240 times the current
flowing into SET. LED3 is high impedance when EN is low.
LED 2 Cathode Connection. Current flowing into LED2 is 240 times the current
flowing into SET. LED2 is high impedance when EN is low.
LED 1 Cathode Connection. Current flowing into LED1 is 240 times the current
flowing into SET. LED1 is high impedance when EN is low.
