LIN Mini System Basis Chip with integrated voltage regulator

The TJA1128 is a mini system basis chip (SBC) that integrates a LIN transceiver, low-dropout voltage regulator (LDO), window watchdog, wake-up inputs, and system control functions for automotive applications. The TJA1128 provides a voltage regulator with 3.3 V or 5.0 V output options and delivers up to 85 mA to support microcontrollers and peripheral devices. The device supports very low-current Standby and Sleep modes with local and LIN bus wake-up capability, helping optimize power consumption in automotive electronic control units (ECUs).
