ATA663454-GDQW

ATA663454-GDQW is a full duplex LINbus transceiver from Microchip Technology, designed for single-wire LIN bus communication in automotive and industrial applications. The device integrates one driver and one receiver (1/1), providing 100 mV of receiver hysteresis for improved noise immunity. It operates over a wide supply voltage range of 5V to 28V and is specified for an extended temperature range of -40°C to 150°C, making it suitable for harsh environments.

The transceiver is housed in a compact 16-VDFN exposed pad package (5.5mm x 3mm) for surface mount assembly. The exposed pad aids in thermal dissipation, supporting the high-temperature operation. The LIN protocol implementation ensures compliance with LIN bus standards for low-cost serial communication networks typically used in body control modules, sensors, and actuator interfaces.

With full duplex capability, the device can transmit and receive simultaneously, though LIN is typically half-duplex; the full duplex likely refers to the transceiver's ability to handle separate TX and RX paths. The receiver hysteresis of 100 mV helps reject noise on the bus line. The wide supply range accommodates various battery voltages in automotive systems.
