TI Intros TPIC1021 Local Interconnect Network Transceiver


New Products Oct 19, 2004 by Jeff Shepard

Texas Instruments Inc. (TI, Dallas, TX) introduced its TPIC1021 stand-alone local interconnect network (LIN) transceiver for automotive applications with electrostatic discharge protection of up to 17 kV and 12 kV. The device survives International Standards Organization 7637 transients and has fault protection to handle -40 V to +40 V on the LIN bus, making it suitable for the harsh automotive environment of low-speed, in-vehicle networks.

The TPIC1021 can also be used with resistance-capacitance, oscillator-based, microcontroller systems, which enables the next generation of LIN-based automotive body applications such as door modules, window lifters, seat controls, intelligent sensors and intelligent actuators.

The TPIC1021 functions across the LIN 2.0 specified data rate up to 20 KB/sec and functions equally well at the lower data rates recommended by SAE J2602. The low power mode minimizes current consumption, and to minimize electromagnetic emissions the TPIC1021 controls the LIN bus slew rate according to the LIN 2.0 standard. To maximize electromagnetic immunity, the receiver’s input filter reduces radio-frequency interference caused by interference on the LIN bus line.

The TPIC1021D is available in an eight-pin, small outline package. Pricing in 1,000-piece quantities is $0.55 each.
