SiLM42281-AQ
Overview
SiLM42280/1/2/3-AQ family devices provide independent 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 individual current configuration and independent digital PWM dimming per channel (e.g. for RGB).
- Three independent linear current drivers (3*150mA)
- Parallel output operation for up to 450mA
- Low power standby / sleep mode
- Thermal management option per channel
- Operating input voltage range 5V to 25V, max up to 40V
- External reference voltage for derating supported
- PWM dimming (All channels or separate channels)
- Diagnostic functionalities (LED Driver open/short, single LED short, IR configuration open/short, Junction temperature, supply voltage)
- Diagnostic bus to link ICs
- Single LED short threshold configuration
