Overview

The Microchip'sATA664151-WNQW is a system basis chip with an eight-channel high voltage switch interface, a LIN 2.1 and SAEJ2602-2-compliant LIN transceiver, low-drop voltage regulator, and an adjustable Window Watchdog. The Microchip ATA664151-WNQW provides 5V output voltage with up to 80mA current capability. This chip combination makes it possible to develop inexpensive, simple, yet powerful slave and master nodes for LIN bus systems. The Microchip ATA664151-WNQW is especially designed for LIN switch applications and includes almost the entire LIN node. They are designed to handle low data-rate communication in vehicles (such as in convenience electronics). Improved slope control at the LIN driver ensures secure data communication up to 20kBaud. Sleep Mode and Active Low-power Mode guarantee minimal current consumption even in the case of a floating bus line or a short circuit on the LIN bus to GND.
