LIN mini system basis chip
Rev. 1 — 29 March 2018
Product data sheet
1 General description
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.
2 Features and benefits
2.1 General
Battery operating voltage range from (3.3 V) 5.0 V to 28 V
Very low current consumption in SLEEP and STANDBY mode
SLEEP mode (voltage regulator off): typically 14 µA
STANDBY mode (voltage regulator on): typically 22 µA
Remote wake-up capability via pin LIN
Local wake-up via pins WAKE1 and WAKE2
Configurable level-sensitive wake-up detection
Cyclic sampled wake-up detection option with synchronized bias control via pin
Wake-up source recognition
Configurable high-voltage multipurpose output (HVMPO)
Bias control output for cyclic wake-up
Limp home output
Bias control output for battery monitoring circuit
General purpose input (GPI) controlled output
Limp home function on overtemperature, watchdog service fail, VCC undervoltage and
RSTN short-circuit to ground
Overtemperature shutdown
Bidirectional reset pin with variable power-on reset length
2.2 Device customization
Quasi one-time configuration via Serial Peripheral Interface (SPI)
Initial mode to configure and disable
Functions (e.g., LIN, watchdog, Reset, WAKE)
Modes (e.g., SLEEP)
