TPT1022Q

Automotive Fault Protected Dual LIN Transceiver with TXD Dominant Timeout

Overview

The TPT1022Q is a dual local interconnect network (LIN) physical layer transceiver that is compliant with the ISO 17987-4, SAE J2602 and LIN 2.0, LIN 2.1, LIN 2.2, and LIN 2.2-A physical layer standard. LIN is a low-speed Universal Asynchronous Receiver Transmitter (UART) communication protocol that supports automotive in-vehicle sub-networks.

The device supports LIN networks up to 20 Kbps with an enhanced timing margin. The device converts the transmitted data received at the TXD with an optimized slew rate to minimize the electro-magnetic emission (EME) and reports the state of the LIN bus at the RXD.

As designed, the device features overvoltage and loss of ground protection from −45 V to +45 V, over-temperature shutdown. The device has low-current standby and sleep mode with LIN BUS wake-up capability. The device integrates a pull high resistor for LIN slave applications and ESD protection which allows applications to operate with a reduced dependence on external components. Additionally, all devices include many protection features to enhance the device and network robustness.

The TPT1022Q is available in SOP-14 and DFN3X4.5-14L packages and is AEC-Q100 qualified for automotive applications.
