LIN system basis chip with LED drivers

With an integrated low-drop voltage regulator, the UJA1018 is a LIN 2.0/2.1/2.2/SAE J2602 transceiver that facilitates the development of compact nodes in LIN bus systems. It offers strong Electro Static Discharge (ESD) performance and can withstand high voltages on the LIN bus, supporting robust designs.

UJA1018 is integrated with three high-side switches that are intended to support a variety of applications, including LED control for ambient lighting. The exposed center pad of UJA1018 package provides enhanced performance.
