TLIN1021ADRQ1

The TLIN1021A-Q1 is a Local Interconnect Network (LIN) physical layer transceiver. LIN is a low-speed Universal Asynchronous Receiver Transmitter (UART) communication protocol that supports automotive in-vehicle networks. The TLIN1021A-Q1 transmitter supports a data rate of up to 20 kbps. The transceiver controls the state of the LIN bus through the TXD pin and reports the bus state through its open-drain RXD output pin. The device features a current-limiting waveform shaping driver to reduce Electromagnetic Emission (EME). The TLIN1021A-Q1 is designed to support 12V applications and has a wide input operating voltage range. The device supports a low-power sleep mode and can be awakened from the low-power mode through the wake-up function from the LIN, WAKE pin, or EN pin. The device can selectively enable various power supplies that may exist on the node through the TLIN1021A-Q1 INH output pin, thereby reducing battery current consumption at the overall system level. The TLIN1021A-Q1 integrates a resistor for LIN responder node applications that provides ESD protection and fault protection, reducing the number of external components in the application. Once a ground drift or power supply voltage disconnection occurs, the device prevents feedback current from flowing through the LIN to the power input. The TLIN1021A-Q1 also includes undervoltage detection, overheat shutdown protection, and ground fault protection functions. Once a fault condition occurs, the transmitter will immediately shut down and remain off until the fault is eliminated.
