TJA1128

TJA1128 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 lowdropout 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 HVMPO 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 Quas...
