LIN-Controlled Alternator Voltage Regulators

KSR offers local interconnect network (LIN) controlled voltage regulator for a range of vehicle alternators that optimizes performance in intelligent automotive charging systems for increased efficiency and improved fuel economy.

As vehicle manufacturers move to integration of a single line, low speed, low cost communication bus, KSR has worked closely with customers on alternator-regulators with the LIN interface. Used when dynamic control of the alternator output and torque is desired for optimal battery charging, electrical system power management and alternator-engine interaction, dynamic alternator control enables improved electrical system efficiency and reduces engine idle speed for greater fuel economy.
In contrast to analog interfaces, the KSR platform offers integrated programmable load response control features, programmable field excitation of current or temperature and regulator feedback of fault status. As an added benefit, our LIN solution can be uniquely addressed for compatibility with up to 15 other modules on the bus and all data can be transmitted or received in a single pass.

Technical highlights include:
• An interface that provides a simplified method of reliably achieving the bi-directional communication required for maximum alternator performance in an intelligent charging system.
• Signals transmitted to the ECU from the regulator include field excitation duty cycle, current or temperature (customer-defined) and the fault status.
• The KSR LIN-controlled alternator regulator is assembled using thick-film hybrid technology for reliable high temperature operation and excellent parametric stability over the entire operating temperature range of -40ºC to 150ºC. Thick-film technology also enables precise laser trimming of discrete resistors so that patented current sensing technology can be used to achieve the highest tolerance capability in the industry.


KSR is an industry leader in the design, engineering and manufacture of an array of products for the transportation industry (autos, light trucks, ATVs), including automotive sensors, electronic throttle controls, adjustable and fixed pedals, electric steering control units and power modules
