Pin Descriptions
PIN NUMBER
1
PIN NAME
ADDR1
PIN FUNCTION
Digital Input. I²C Address select bit 1, used with ADDR0 to select the ISL59911 I²C address (see “ISL59911 Serial
Communication” on page 13).
Note: If power supply sequencing cannot be guaranteed, ADDR1 must be held low during power-up.
See “Power Supply Sequencing” on page 10 for more information.
