IRVR101
Introduction
The IRVR101 is designed for use in a 12V automotive charging system where optimized battery charging and
dynamic alternator control are desired. The Block Diagram illustrates the main components and potential
system configuration of the LIN controlled charging system. The regulator is shown separate from the
alternator assembly but it is typically integrated into the machine. The interface between the Engine Control
Unit (ECU) and the regulator requires one bi-directional line with a transceiver at each end for serial
communication. Alternatively, communication may be achieved between the regulator and Body Control
Module (BCM) as illustrated in below.
The signals to the regulator (received from the ECU or BCM) include the voltage setpoint, load response control
ramp, load response control ramp cut-off speed, and the field excitation limit. The voltage setpoint command
also allows for disabling of the field driver to achieve a momentary no output condition. Signals from the
regulator (transmitted to the ECU or BCM) include the field excitation duty cycle, the field excitation current OR
temperature (customer defined), and the fault status. Transmitted fault codes provide unique indication for
mechanical, electrical, temperature, communication, and timeout errors.
