LIN System Basis Chip with LED Drivers
The UJA1018 is a LIN 2.0/2.1/2.2/SAE J2602 transceiver with an integrated low-drop voltage regulator. The voltage regulator can deliver up to 70 mA at 5.0 V. The UJA1018 facilitates the development of compact nodes in LIN bus systems. In addition, the UJA1018 supports LIN node address assignment in daisy chain networks via a LIN bus switch. To support robust designs, the UJA1018 offers strong Electro Static Discharge (ESD) performance and can withstand high voltages on the LIN bus. In order to minimize current consumption, the UJA1018 supports a Sleep mode in which the LIN transceiver and the voltage regulator are powered down while still having wake-up capability via the LIN bus.
Three high-side switches are integrated into the UJA1018. They are intended to support a variety of applications, including LED control for ambient lighting.
The UJA1018 comes in a 3.5 mm x 5.5 mm HVSON16 package to help minimize board size. The exposed center pad in the HVSON16 package provides enhanced thermal performance.
