Microchip ATA663454-GDQW

ТрансиверLINbus

Overview

The Microchip'sATA663431/54 system basis chip is a fullyintegrated LIN transceiver, designed according to the LIN specification 2.0,2.1, 2.2, 2.2A and SAEJ2602-2, with a low-drop voltage regulator with 3.3V/85mA(ATA663431) or 5V/85mA (ATA663454). Additional the device includes a Watchdog, a high-side switch and 2 high-voltage wake inputs: one positive edge sensitive, one negative edge sensitive. This combination makes it possible to develop simple but powerful slave nodes inLIN bus systems. Improved slope control at the LIN driver ensures secure datacommunication up to 20Kbaud. Sleep mode and silent mode guarantee minimizedcurrent consumption even in the case of a floating or a shorted LIN bus. Thevoltage regulator is a fully integrated low-drop regulator working down to asupply voltage of 2.3V with best-in-class current consumption in linear mode(2V
