ATA663454中文资料LIN System Basis Chip Including 5V Voltage Regulator, Watchdog and High Side Switch数据手册Microchip规格书

描述 Description

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
The device is available in DFN16 package with wettableflanks to enable optical soldering inspection. The footprint is compatible withthe ATA663231/54 LIN system basis chip which enables customers to producemodules with/without watchdog by assembling the LIN SBC with watchdog(ATA663431/54) or the ATA663231/54 without watchdog.
