Overview

The TPT1028xQ is a local interconnect network (LIN) system basis chip (SBC), which includes a LIN transceiver, compliant to the ISO 17987-4, SAE J2602 and LIN 2.0, LIN 2.1, LIN 2.2, and LIN 2.2-A physical layer standard, and an integrated low drop out (LDO) voltage regulator. LIN is a low-speed Universal Asynchronous Receiver Transmitter (UART) communication protocol that supports automotive in-vehicle sub-networks.

The LIN SBC is designed in LIN networks up to 20 Kbps and reduces system complexity by providing a 5-V or 3.3-V LDO to power microprocessors, sensors, and other devices. The device supports Sleep mode, in which the LDO and LIN transceivers are shut down while still able to be woken up via the LIN bus. 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. With an optimized circuit design, the TPT1028xQ exhibits very low electromagnetic emission (EME) and high electromagnetic immunity (EMI) capabilities.

As designed, the device features overvoltage and loss of ground protection from −45 V to +45 V, over-temperature shutdown, under voltage and short to ground protections, and other protection features to enhance the device and network robustness.

The TPT1028xQ is available in SOP-8, ESOP-8, and DFN3X3-8 packages and is AEC-Q100 qualified for automotive applications.
