Multifunction Alternator Regulator The TC80500 is an integrated circuit intended to regulate the output voltage of an automotive alternator. It supplies a current via a high-side MOSFET to the excitation coil of the alternator and provides an internal freewheeling diode. It allows keeping the battery at its nominal charge and delivering current to electrical devices within the vehicle. Freescale can program the device to fit a large number of alternator applications and to adapt to the warning indicator used (either Lamp or LED). To temporarily manage the important alternator output current variation and limit torque variation, the IC provides a load response control mechanism (LRC). This device is powered by SMARTMOS technology.
