Typical Applications
L9616-TR is suitable for 6 applications: Automotive Body Control Module, Industrial Sensor Network, Aftermarket Automotive Electronics, Smart Lighting Systems, Telematics and Fleet Management, Electric Vehicle Battery Management.
Automotive Body Control Module
The L9616-TR is used in body control modules to interface with LIN-based sensors and actuators. Its wide supply voltage range (5V-27V) and robust protection features ensure reliable operation in automotive environments. The transceiver connects directly to the microcontroller's UART, enabling communication with door modules, window lifts, and mirror controls. Its low quiescent current (10 uA) in sleep mode helps reduce battery drain when the vehicle is off. The thermal shutdown and short-circuit protection prevent damage from bus faults, making it ideal for harsh automotive conditions.
Recommended
Industrial Sensor Network
In industrial settings, the L9616-TR enables low-cost, single-wire communication between sensors and a central controller. Its data rate of up to 20 kbps is sufficient for transmitting sensor readings such as temperature, pressure, and position. The wide operating temperature range (-40C to +125C) allows deployment in harsh factory environments. The transceiver's ESD protection (Β±8 kV HBM) ensures robustness against electrostatic discharge during installation and maintenance. The INH pin can be used to control an external regulator, enabling power management in battery-powered sensor nodes.
Recommended
Aftermarket Automotive Electronics
The L9616-TR is widely used in aftermarket automotive electronics such as car alarms, remote start systems, and diagnostic tools. Its compatibility with LIN 2.x and SAE J2602 ensures interoperability with OEM vehicle networks. The transceiver's small SO-8 package allows for compact PCB designs, fitting into tight spaces behind dashboards or in door panels. The wake-up capability via the LIN bus enables the system to remain in low-power mode until a command is received, extending battery life. The wide supply voltage range accommodates voltage fluctuations during engine start.
Recommended
Smart Lighting Systems
The L9616-TR is used in smart lighting systems for automotive and architectural applications. In automotive lighting, it enables communication between the central lighting control module and LED drivers, allowing dynamic lighting features such as adaptive headlights and ambient lighting. The transceiver's high data rate (20 kbps) is sufficient for real-time control commands. Its robust protection features ensure reliable operation in the presence of electrical noise from the vehicle's electrical system. The low quiescent current is beneficial for lighting systems that remain in standby mode when not in use.
Recommended
Telematics and Fleet Management
The L9616-TR is used in telematics units for fleet management, enabling communication between the vehicle's LIN network and a central tracking system. The transceiver's wide supply voltage range (5V-27V) allows direct connection to the vehicle battery, while its low quiescent current (10 uA) minimizes battery drain when the vehicle is parked. The wake-up capability via the LIN bus allows the telematics unit to remain in sleep mode until a bus message is received, reducing power consumption. The ESD protection ensures reliability in the harsh automotive environment.
Recommended
Electric Vehicle Battery Management
The L9616-TR is used in electric vehicle battery management systems (BMS) to communicate between battery monitoring units and the central BMS controller. Its wide operating temperature range (-40C to +125C) is essential for battery packs that experience extreme temperatures. The transceiver's robust protection features, including short-circuit and thermal shutdown, ensure safe operation in high-voltage environments. The low quiescent current helps extend the battery life of the BMS when the vehicle is off. The LIN bus provides a cost-effective communication medium for distributed battery monitoring.

Key Differentiators
- Wide supply voltage range (5V-27V) (vs MCP2003)
- Low quiescent current (10 uA) (vs TJA1020)
- STMicroelectronics quality and support (vs TJA1020)
Design Notes
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 1kΞ©) 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.
Compliance Information
RoHS compliant per STMicroelectronics product page. Not AEC-Q100 qualified; choose TJA1020 for automotive qualification.
