Patent number: 7242227Abstract: A differential bus network, in general, or a controller area network (CAN) driver, in particular, controls and minimizes the variation on the common-mode signal of the CAN bus. This CAN driver also provides improved symmetry between its differential output signals, CANH and CANL, and provides protection for its low voltage devices from voltage transients occurring on its output lines. The common-mode signal is sensed and buffered, then during the dominant to recessive transition, the bus signals are shorted to the buffered common mode voltage. Specifically, additional switches or transistors are used to pull the differential output signals, CANH and CANL, to the common mode signal VCM when the state of the CAN bus transitions from dominant to recessive. This improvement minimizes high frequency spikes in the common-mode signal and eliminates DC shifts during transitions of the state of the CAN bus.Type: GrantFiled: November 1, 2004Date of Patent: July 10, 2007Assignee: Texas Instruments IncorporatedInventors: Timothy P. Pauletti, John H. Carpenter, Jr., Wayne Tien-Feng Chen

Patent number: 7224202Abstract: A high voltage level shifter having a cost effective design that saves chip architecture and power. The high voltage level-shifter includes a resistor connected between a first node and a first power supply rail. An inverter couples to receive an input signal to provide an inverted input signal. A first circuit portion couples to receive the inverted input signal and connects between the first power supply rail and a second power supply rail for converting a high voltage signal into a low voltage signal. The first circuit portion includes a first clamp circuit, wherein the first circuit portion is biased through the first clamp circuit and the first node. A second circuit portion couples to receive the input signal and connects between the first power supply rail and a second power supply rail for converting a low voltage signal into a high voltage signal.Type: GrantFiled: November 3, 2004Date of Patent: May 29, 2007Assignee: Texas Instruments IncorporatedInventor: Timothy P.

Publication number: 20040119517Abstract: A wake-up circuit for a ECU on a ECN utilizes two complementary switching transistors which will turn ON when there is a differential voltage between CANH and CANL which will turn ON the transistors to pass a current which will be mirrored over to create a voltage which will switch a comparator or a Schmitt trigger. The two signals are then ORed together to generate a digital wake-up signal that can be utilized by other on-chip circuitry.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Inventors: Timothy P. Pauletti, John H. Carpenter, Benjamin L. Amey
