TPIC1021AQDRQ1

The TPIC1021A-Q1 is a LIN physical interface transceiver from Texas Instruments, designed for low-speed, in-vehicle networks. It complies with LIN physical layer specification revision 2.0 and SAE J2602.

This transceiver supports LIN bus speeds up to 20 kbps and features ultra-low current consumption in sleep mode, with wake-up capabilities from the LIN bus, an external switch, or the host MCU. It offers high-speed receive capability and robust protection features, including ±12 kV ESD protection on the LIN pin, and the LIN pin handles voltages from -40 V to 40 V. The device is designed to survive transient damage in automotive environments per ISO 7637.

Operating with a supply voltage from 7 V to 27 V DC, it interfaces with MCUs using 5-V or 3.3-V I/O pins. Additional features include dominant state time-out protection, wake-up request on RXD pin, control of an external voltage regulator via the INH pin, and an integrated pullup resistor and series diode for LIN responder applications. It exhibits low electromagnetic emission (EME) and high electromagnetic immunity (EMI).

The TPIC1021AQDRQ1 is housed in an 8-pin SOIC package suitable for surface mounting. It operates within an ambient temperature range of -40°C to 125°C. The part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS'.
