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.Features Dual or mono phase self-start operation Internal freewheeling diode Up to 8.0 A rotor current(excitation coil)Load response control(LRC)Thermal protection and temperature compensation LED/lamp driver(warning function)Timer,progressive load,LRC duration,LRC disable frequency Field monitor frequency,FM clamp,filtering and type Auxiliary load activation Sense Reference Voltage Switch(RVS)Pre-excitation duty cycle Six or eight pairs of poles Wide Open Throttle(WOT)and Powertrain functions Config1 Config2 Config3 Vreg 14.5 14.5 14.5 Number of poles for IIR filter 1 pole filter 1 pole filter 1 pole filter CPR/LRC LRC LRC LRC Spread spectrum no no no FM clamp 1.5%-98.5%1.5%-98.5%1.5%-98.5%FM frequency(Hz)112.5 Hz 112.5 Hz 71 Hz FM type FR FR FR Lamp/LED Lamp Lamp Lamp LRC disable(RPM)3100 rpm 3100 rpm 3100 rpm Min_DC(%)1.5%1.5%1.5%Phase number 2 1 1 Nslefstart(rpm)3100 rpm 3100 rpm 1920 rpm Nstart(rpm)1200 rpm 1200 rpm 1200 rpm Pair of poles 6 6 6 Pre_Exc DC(%)29%29%12.5%PWT Inactive Inactive Inactive Ramp type 250mV/160steps 250mV/160steps 200mV/128steps RVS/Sense RVS RVS RVS TC(mV/C)-7mV/C-7mV/C-3.5mV/C Tlrc/cp 5s 5s 5s Th gradient No gradient No gradient refresh every Tlrc/4 WOT Inactive Inactive Inactive AUX Auxiliary load used Auxiliary load used Auxiliary load used Sense Sense pad used Sense pad used Sense pad used Timer 0sec 0sec 2.5sec 注意：系统电源电压超过 40V 需要做过压保护；产品技术联系人：肖工 13911569774 QQ434572980 PIN Name:HSOP28
