描述 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.

特性 Features

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.
