3 / 9 page UAC33092 LINEAR INTEGRATED CIRCUIT UNISONICTECHNOLOGIESCO.,LTD 3 of 9 www.unisonic.com.tw QW-R101-017,C PIN DESCRIPTION 20-pin Package 24-pin Package PIN No. PIN NAME DESCRIPTION 1 1 FB This pin provides a filtered result of the Sense input (if the Sense input is used) or the Supply Regulation input (if the Sense input is not used). 2 2 Sense The Sense input is a remote, low current battery voltage reference input used to give an accurate representation of the true battery voltage. This input is also used to monitor overvoltage or load dump conditions. 3 3 Lamp Collector and Power-Up/Do wn This pin connects to the collector of the transistor (Q2) used to drive the fault lamp. It is also used to sense a closed ignition switch (voltage sense) which then turns power on to the IC. 4 4 Lamp Base The Lamp Base pin provides base current to the fault lamp drive transistor (Q2). 5 5 Ground Grounded to provide a ground return for the fault lamp control logic circuit. 6, 15 6,15 Ground IC ground reference pins. 7 7 Oscillator Adjust A resistor to ground on this pin adjusts the internal oscillator frequency. 8 8 VREF0 This is a test point for the 1.1V to 1.4V reference voltage. It has a zero temperature coefficient. The reference is used internally for phase signal and undervoltage detection. 9 9 Oscillator Test point for checking the operation of the internal oscillator. 10 10 Phase The Phase input detects the existence of a magnetic field rotating within the alternator. 11 11 Rate The Rate pin is used to select a slow mode (floating) or fast mode (ground) Load Response Control recovery rate. 12 12 Supply Regulation The voltage on the Supply Regulation pin is used as a representation of the alternator output voltage. This input also used to monitor overvoltage or load dump conditions. 13 13 VCC3 Positive supply for the internal Charge Pump. 14 14 VCC1 Positive supply for the entire IC except for the Charge Pump. 15,6 15,6 Ground Ground reference for the IC. 16 16,17,18, 19,20 N/C No connection. 17 21 Gate Controls the Gate of the MOSFET used to energize the field winding. 18 22 Source Field winding control MOSFET source reference. 19 23 Undervoltage If the voltage at this pin goes below 1.0 V, the fault lamp is guaranteed to turn on. The IC will continue to function, but with limited performance. 20 24 VREF Test point for the 1.7 V to 2.3 V Band gap reference voltage. This voltage has a negative temperature coefficient of approximately –11 mV/℃ Note: Pins 8, 9, 20(20 Pin Package) and 24(24 Pin Package) are test points only. |
