● Function Description
(1) LED driver
? UPIC interface
BD1601MUV is a single line digital interface control (Uni-port Interface Control=UPIC) that can control the power
ON/OFF and LED current value through the EN pin only. The LED current increments by about 0.5mA depending on
the number of leading edges. When the number of leading edge is added at the maximum output current of 30mA (64
leading edges), the current is almost equal to 0.5mA at startup time. To maintain any output current, the EN pin must
be kept at “H” level. To power off, the EN pin must be kept at “L” level for more than 640μsec.

? LED current level
The LED current state can be changed by the EN control signal. When the current level is Cn, the basic LED current
(ILED) can be obtained from the following expression (where, n indicates a state number).
