Datasheet
● LED current setting range
LED current can set up Normal and Starting setting current.
LED current can set up Normal current by resistance value (RISETH) connecting to ISETH voltage and LED current can set
Starting current by resistance value (RISETL) connecting to ISETL voltage.
Setting of each LED current is given as shown below.
Normal current = 20mA (24k ? /RISETH) Starting constant current = 0.6/RISET L
Also, Normal current setting range is 10mA to 25mA, Starting current setting range is OFF setting or 1μA to 100μA.
LED current can set OFF setting by open setting ISETL pin.
LED current becomes a leak current MAX 1μA at OFF setting.

● The separations of the IC Power supply and coil Power supply
This IC can work in separating the power source in both IC power supply and coil power supply. With this application, it can
obtain that decrease of IC power consumption, and the applied voltage exceeds IC rating 22V.
That application is shown in below Fig 44. The higher voltage source is applied to the power source of coil that is connected
from an adapter etc. Next, the IC power supply is connected with a different coil power supply. Under the conditions for
inputting from 2.7V to 5.5V into IC VBAT, please follow the recommend design in Fig 40. It connects VBAT terminal and
VREG terminal together at IC outside.
When the coil power supply is applied, it is no any problem even though IC power supply is the state of 0V. Although IC
power supply is set to 0V, pull-down resistance is arranged for the power off which cuts off the leak route from coil power
supply in IC inside, the leak route is cut off. And, there is no power on-off sequence of coil power supply and IC power
supply.
