The SN65MLVD048RGZR is an integrated local interconnect network (LIN) transceiver designed to operate in the LIN physical layer, compliant with the LIN 2.2 protocol. It is used in applications such as industrial automation, automotive, and home appliances.This transceiver combines the physical layer transceiver function and the serial interface circuitry needed for communication on a single chip. By incorporating both the transceiver and the interface blocks into a single chip, the SN65MLVD048RGZR allows for boosted data rates, reduced electromagnetic interference (EMI) due to a reduced pin-count for serial communications, and reduced board space. The SN65MLVD048RGZR also includes current sensing of the LIN bus, which can be used to directly monitor the activity on the LIN bus, without the need for additional peripherals or components.

The SN65MLVD048RGZR’s bus transceiver section is designed using Bipolar technologies. It utilizes two power transistors to drive the bus at up to 40V, with a maximum current of 150 mA. This makes it suitable for operation in harsh automotive environments, with high electromagnetic interferences and temperatures ranging from -40°C up to 105°C.

The SN65MLVD048RGZR incorporates a low-dropout regulator for the supply rail of the on-chip logic and improved logic supply rejection, which allows for reliable operation over an extended voltage range. The transceiver supports a wide variety of data rates, up to 20 kbit/s. It supports functional test features as well as compatibility with both 5V/3.3V and 12V/24V battery systems.

The SN65MLVD048RGZR also has two separate sets of receiver and transmitter pins, which offer improved signal detection and error detection accuracy. The transceiver is equipped with a standard slew-rate limiter, allowing for an optimized voltage swing for data transfer and reducing EMI emission and signal reflections on the LIN bus.

The SN65MLVD048RGZR transceiver features an integrated protection circuit to protect the connected components from voltage and current overloads, including a thermal protection circuit to prevent damage from excessive temperatures, and an electrostatic discharge (ESD) protection circuit. It also features a LIN bus state monitor and Auto-wakeup circuitry for wake up-message transmission and reception on the LIN bus.

The SN65MLVD048RGZR transceiver is ideal for applications such as embedded systems, automotive infotainment systems, industrial automation and power management, motor control systems, and home appliances. It is also suitable for use in Medical applications, as it is designed to meet the stringent requirements of AEC-Q100 Grade 2 and can withstand the high temperatures and radiation exposure found in these environments.

The SN65MLVD048RGZR transceiver is an ideal solution for a wide variety of applications, as it combines the robust transceiver characteristics of the LIN bus, high speed data rates and advanced protection circuitry, all combined into a single chip. The integrated protection circuits and the wide range of features make it an ideal choice for applications in the automotive, industrial and consumer markets.
