General Description
E522.84/85/86/87 family devices provide triple linear current controller for LED driving (standalone driver or LED cluster). Diagnostic features are provided to meet automotive requirements, together with a communication interface “RUN” to link ICs to generate more than three channels, supporting common current configuration per IC and including digital PWM dimming via fast ENA.
FEATUREs
◾ Three integrated Linear Current Drivers (3*60mA)
◾ Parallel Output Operation for up to 180mA
◾ Low Power Standby / Sleep Mode
◾ Operating Input Voltage Range 5V to 25V, max. 40V
◾ External Reference Voltage / Derating Supported
◾ Common PWM Dimming (All channels in parallel)
◾ Diagnostic Functionalities (LED Driver Open/Short,
