Triple 60mA Linear LED Controller
Preliminary Information - Jan 21, 2015
E522.84/85/86/87
4 Electrical Characteristics
(VVS = 5V to 25V, TJ= -40°C to +150°C and recommended operating range, unless otherwise noted. Typical values are at VVS
=
14V and TJ = 25°C. Positive currents flow into the device pins.)

Notes on table section Supply and Bias
1) See state diagram in chapter „5.4 State Diagram“ for details
2) Please note, that in case of LED or IR shortcircuit the average input current also depends on the configured current and the re-diagnostic du-
tycycle. Example: In case of a single LED short to GND the current at VS in SLM is typ. approx. 100µA plus 64/5900*ILEDx
