UJA1018
LIN system basis chip with LED drivers
Rev. 1 — 10 July 2012
Product data sheet
1. General description
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 ElectroStatic 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 5.5 mm HVSON16 package to help minimize board
size. The exposed center pad in the HVSON16 package provides enhanced thermal
performance.
