UAC3092 Datasheet | Unisonic Technologies

UNISONIC TECHNOLOGIES CO., LTD UAC3092 ALTERNATOR VOLTAGE REGULATOR DESCRIPTION The UAC3092 is specifically designed for voltage regulation and Load Response Control (LRC) of diode rectified alternator charging systems, as monly found in automotive applications. In maintaining system voltage, the UAC3092 monitors and pares the system battery voltage to an externally programmed set point value and pulse width modulates an N- channel MOSFET transistor to control the average alternator field current. LINEAR INTEGRATED CIRCUIT SOP-20 SOP-24 FEATURE - Forced Load Response Control (LRC) with Heavy Load Transitions at Low RPM - Capable of Regulating Voltage to 0.1 V @ 25 - Operating Frequency Selectable with One External Resistor - < 0.1 V Variation over Speed Range of 2000 to 10,000 RPM - < 0.4 V Variation over 10% to 95% of Maximum Alternator Output - Maintains Regulation with External Loads as Low as 1.0 A - Load Dump Protection of Lamp, Field Control Devices, and Loads .. - Duty Cycle Limit Protection - Provides High Side MOSFET Control of a Ground Referenced Field Winding - Controlled MOSFET and Flyback Diode Recovery Characteristics for Minimum RFI - Optional 2.5 or 10 sec. LRC Rate Control (Osc. Freq. = 280 k Hz) - Undervoltage, Overvoltage and Phase Fault (Broken Belt) Detection - Pb-free plating product number: UAC3092L ORDERING INFORMATION Order Number Normal Lead Free Plating UAC3092-S20-R UAC3092L-S20-R UAC3092-S20-T UAC3092L-S20-T UAC3092-S24-R UAC3092L-S24-R UAC3092-S24-T UAC3092L-S24-T Package SOP-20 SOP-20 SOP-24 SOP-24 Packing Tape Reel Tube Tape Reel Tube UAC3092L-S20-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) S20: SOP-20, S24: SOP-24 (3) L: Lead Free Plating, Blank: Pb/Sn .unisonic..tw Copyright © 2005 Unisonic Technologies Co., Ltd 1 of 9 QW-R121-003,B PIN CONFIGURATIONS LINEAR INTEGRATED CIRCUIT 20-pin...
