Quad LIN Commander Transceiver for In-Vehicle Subnetworks
LIN Mini System Basis Chip
The TJA1128 is a LIN mini system basis chip (SBC) with a LIN transceiver, a low-dropout voltage regulator (LDO), a window watchdog, two WAKE inputs, one general purpose input (GPI) and one high-voltage multipurpose (HVMPO) output.
The voltage regulator delivers up to 85 mA and is available with 3.3 V and 5.0 V output voltages. The TJA1128 can be operated in very low-current standby and sleep modes with bus and local wake-up capability.
