TJA1128 Datasheet | NXP Semiconductors

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 m A 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 - 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) NXP Semiconductors LIN mini system basis chip 2.3 Low-dropout voltage regulator for 3.3 V/5.0 V microcontroller supply - 5.0 V/3.3 V nominal output voltage, ±2 % accuracy - 85 m A output current capability - Undervoltage detection with reset output - Excellent transient response with a small ceramic output capacitor - Output is short-circuit proof to GND 2.4 LIN transceiver - ISO 17987-4:2016 (12 V LIN)...
