TJA1128
Overview
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.
- 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
