Technical Note
Function
Power Supply Terminal
I²C Slave-address Terminal
ADDR = ‘H’ ( ADDR ≧ 0.7VCC )
“1011100“
ADDR = 'L' ( ADDR ≦ 0.3VCC )
“0100011“
ADDR Terminal is designed as 3 state buffer for
internal test. So that please take care of VCC
and DVI supply procedure.Please see P6.

SCL
※These values are design-value, not guaranteed.
I²C bus Interface SDA Terminal
SDA, SCL Reference Voltage Terminal
And DVI Terminal is also asynchronous Reset
for internal registers.So that please set to 'L'
( at least 1µs, DVI <= 0.4V ) after VCC is
supplied. BH1750FVI is pulled down by
150kOhm while DVI = 'L'.
