The setpoint control is achieved using the Local Interconnect Network (LIN) serial munications protocol. Slew rate control and filtering of the interface lines provide electromagnetic patibility. The regulator consists of a control ASIC, discrete low side power MOSFET (field driver), re-circulation diode, and passive ponents. 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 o C to 150 o C. Design The IRVR101 is manufactured using thick-film hybrid technology. The hybrid circuit can be customized for your application to optimize performance and reliability. The hybrid circuit can also be assembled in a custom housing with an insert- molded leadframe specifically designed for flame-soldering or heavy wire bonding. Thick-film hybrid technology offers reliable high temperature operation with excellent parametric stability over the entire operating temperature range. Resistor values are trimmed within +/-1% using laser equipment that provides precise calibration of voltage and current sensing circuitry. The control IC is attached to the substrate using flip chip technology in order to optimize space and reliability. Bare die is also used for the low side field driver and...
