L9616-TR Descripción general
A LIN transceiver is a specialized integrated circuit that provides the physical layer for LIN networks, which are low-cost, single-wire serial communication buses used primarily in automotive body control applications. The transceiver converts the digital signals from the microcontroller's UART into bus-level voltages and vice versa, while providing protection against bus faults, ESD, and electromagnetic interference. In the system hierarchy, the LIN transceiver sits between the microcontroller (protocol layer) and the physical bus wire, forming the lowest layer of the LIN protocol stack.
Key features of the L9616-TR include a wide operating voltage range of 5V to 27V, making it compatible with automotive battery voltages, and a low quiescent current for power-saving in standby modes. The device supports both normal and standby operating modes, with a wake-up capability via the bus line. It also features thermal shutdown and short-circuit protection, ensuring robust operation in harsh automotive environments. The SO-8 package provides a compact footprint with a thermal resistance of approximately 150 C/W, suitable for moderate power dissipation.
The L9616-TR is built using STMicroelectronics' high-voltage BCD (Bipolar-CMOS-DMOS) technology, which integrates robust analog and digital circuitry on a single die. This technology enables the transceiver to handle high bus voltages and transient conditions while maintaining low power consumption. The device is fully compliant with the LIN 2.x and SAE J2602 standards, ensuring interoperability with other LIN nodes.
Typical applications include automotive body control modules, door modules, seat control, steering column switches, and industrial sensor networks. The L9616-TR is also used in aftermarket automotive electronics and diagnostic tools. Its wide input voltage range and robust protection features make it ideal for direct connection to the vehicle battery.
When designing with the L9616-TR, ensure proper bus termination (typically 1kΩ to 10kΩ pull-up to battery) and place a 100nF bypass capacitor close to the VCC pin. The TXD and RXD pins interface directly with the microcontroller's UART, and the INH pin can be used to control an external voltage regulator for power management in sleep mode.

Diferenciadores clave
- Wide supply voltage range (5V-27V) (frente a MCP2003)

Notas de diseño
Place a 100nF bypass capacitor close to the VCC pin (pin 3) and a 10uF electrolytic capacitor for bulk decoupling. The LIN bus line (pin 5) should have a series resistor (typically 1kΩ) and a diode to protect against reverse polarity. Ensure the ground plane is solid to minimize noise.
The SO-8 package has a thermal resistance of approximately 150 C/W. At maximum supply voltage (27V) and typical bus current, power dissipation is low (less than 0.5W), so no heatsink is required. However, ensure adequate copper area on the PCB for heat spreading.
Do not exceed the absolute maximum ratings: supply voltage 40V, bus voltage -27V to +40V. Ensure the TXD pin is not left floating; pull it high or low as per datasheet. The INH pin can be used to control an external regulator; if unused, connect it to VCC.
