The IRVR101 is an integral alternator voltage regulator that allows for external control of the setpoint voltage in an automotive charging system where optimized alternator output control is desired. The setpoint control is achieved using the Local Interconnect Network (LIN) serial communications protocol. Slew rate control and filtering of the interface lines provide electromagnetic compatibility. The regulator consists of a control ASIC, discrete low side power MOSFET (field driver), re-circulation diode, and passive components. The discrete circuitry allows for optimal flexibility with respect to the alternator rotor circuit and charging system requirements. The IRVR101 is characterized over the temperature range of 40 to 150 .
