LIN2.x Relay Node SBC for 1 Relay | E523.03, E523.04, E523.13, E523.14 (*SBC)

The Elmos System-Basis-Chip (SBC) family E523.03/04/13/14 controls one low-side driven relay or one high-side driven relay. The relay holding current can be programmed by the external micro-controller via the PWM input pins.
The IC provides a LIN 2.x(1.3), SAE-J2602 compliant communication interface or PWM-interface with error feedback capability, which can be accessed by an external micro-controller. Also integrated functions are, system power supply (3.3V or 5V selectable) for an external μC and an independent window-
watchdog.
The IC is configured and controlled over an SPI interface together with one PWM input pin for the relay driver. A set of diagnostic functions is provided, the status information can be read out via SPI. The LIN interface supports a “FLASH Mode” for fast upload of new firmware to the external micro-controller. For fast time-to-market Elmos provides demo-boards as well as design-in support.
