3 Channel Automotive LED Driver | E522.60

E522.60 provides high-voltage linear current drivers suitable for e.g. LED lighting applications up to 3x200mA.
E522.60 features 'one-resistor' common current configuration at reduced effort. Integrated diagnostics support
automotive requirements together with a fault-bus "RUN" to link ICs.
Two external configurable modes of fault handling allow
• "Failure Feedback Mode" FFM operating channels in case of errors, with error signalization
• "Single Lamp Mode" turning all linked E522.60 channels 'off' in case of errors
Integrated phase-shifted PWM dutycycle generation simplifies supply-line filtering in case of dimmed opera-
tion. Low-component-count switching between continuous operation (e.g. STOP light) and PWM dimmed
operation (e.g. TAIL light) is supported.Robust power management is provided per channel to
extend the usable range of supply voltage and/or power- combined with excellent low-drop performance and
flexibility in LED voltage per channel. Simple shunt resistors share power dissipation with the IC package to
reduce temperature of the PCB hotspots.
Derating for internal reference voltage increases robustness of E522.60 systems in case of abnormal operation
conditions. Further flexibility for e.g. advanced thermal handling is provided by analog reference voltages via
high-voltage ENA input.
