Pay attention to the ‘open’ state detection limit „IIR,OPEN“ for IRx configuration 2) high PWM frequencies need to take into account, that there is an inherent startup delay between rising edge at IRx and current flow, which may influence PWM linearity 3) high capacitance values are possible but lead to additional delay between rising edge at ENA and startup of LEDx Drivers 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 Elmos Semiconductor AG reserves the right to change the detail specifications as may be required to permit improvements in the design of its products.
