UTC MC33092 LINEAR INTEGRATED CIRCUIT
ALTERNATOR VOLTAGE
REGULATOR
DESCRIPTION
The MC33092 is specifically designed for voltage
regulation and Load Response Control (LRC) of diode
rectified alternator charging systems, as commonly
found in automotive applications.
In maintaining system voltage, the MC33092
monitors and compares 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.
FEATURE
*Forced Load Response Control (LRC) with Heavy
Load Transitions at Low RPM
*Capable of Regulating Voltage to ± 0.1 V @ 25°C
*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 kHz)
*Undervoltage, Overvoltage and Phase Fault (Broken
Belt) Detection
