Order this document by MC33092A/D The MC33092A is specifically designed for voltage regulation and Load Response Control (LRC) of diode rectified alternator charging systems, as commonly found in automotive applications. The MC33092A provides load response control of the alternator output current to eliminate engine speed hunting and vibration due to sudden electrical loads which cause abrupt torque loading of the engine at low RPM. Two load response rates are selectable using Pin 11. The timing of the response rates is dependent on the oscillator frequency. In maintaining system voltage, the MC33092A 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. • Forced Load Response Control (LRC) with Heavy Load Transitions at Low RPM • Capable of Regulating Voltage to ± 0.1 V @ 25°C • • • • • • • • • • • • ALTERNATOR VOLTAGE REGULATOR SEMICONDUCTOR TECHNICAL DATA 20 Operating Frequency Selectable with One External Resistor < 0.1 V Variation over Speed Range of 2000 to 10,000 RPM 1 < 0.4 V Variation over 10% to 95% of Maximum Alternator Output Maintains Regulation with External Loads as Low as 1.0 A DW SUFFIX PLASTIC PACKAGE CASE 751D (SO–20L) 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 < 2.0 mA Standby Current from Battery @ 25°C < 3.0 mA Standby Current from Battery Over Temperature Range Optional 2.5 or 10 sec.

The system shown in Figure 1 includes an alternator with its associated field coil, stator coils and rectifiers, a battery, a lamp and an ignition switch. A tap is connected to one corner of the stator windings and provides an ac signal for rotation (phase) detection. A unique feature of the MC33092A is the Load Response Control (LRC) circuitry. The LRC circuitry is active when the stator winding ac signal frequency (phase buffer input signal, Pin 10) is lower than the Low/High RPM transition frequency. When active, the LRC circuitry dominates the basic analog control circuitry and slows the alternator response time to sudden increases in load current. This prevents the alternator from placing a sudden, high torque load on the automobile engine when a high current accessory is switched on. The LRC circuitry is inactive when the stator winding ac signal frequency is higher than the Low/High RPM transition frequency. When the LRC circuitry is inactive, the basic analog control circuitry controls the alternator so it will supply a constant voltage that is independent of the load current. Both the LRC and analog control circuits control the system voltage by switching ON and OFF the alternator field current using Pulse Width Modulation (PWM). The PWM approach controls the duty cycle and therefore the average field current. The field current is switched ON and OFF at a fixed frequency by a MOSFET (Q1) which is driven directly by the IC. The MC33092A uses a charge pump to drive the MOSFET in a high side configuration for alternators having a grounded field winding. A fault detector is featured which detects overvoltage, undervoltage, slow rotation or non–rotation (broken alternator belt) conditions and indicates them through a fault lamp drive output (Pin 4). A Load Dump protection circuit is included. During a load dump condition, the MOSFET gate drive (Pin 17) and the fault lamp drive output are disabled to protect the MOSFET, field winding and lamp. Power–Up/Down Power is continuously applied to the MC33092A through VCC1 and VCC3. A power–up/down condition is determined by the voltage on the Lamp Collector pin (Pin 3). When this voltage is below 0.5 V the IC is guaranteed to be in a low current standby mode. When the voltage at Pin 3 is above 2.0 V, the IC is guaranteed to be fully operational. The power–up voltage is applied to Pin 3 via the ignition switch and fault lamp. In case the fault lamp opens, a 500 Ω bypass resistor should be used to ensure regulator IC power–up. A power–up reset circuit provides a reset or set condition for all digital counter circuitry. There is also a built–in power–up delay circuit that protects against erratic power–up signals. Battery and Alternator Output Voltage Sensing The battery and the alternator output voltage are sensed by the remote (Sense, Pin 2), and the local (Supply Regulator, Pin 12) input buffer pins, respectively, by way of MOTOROLA ANALOG IC DEVICE DATA external voltage dividers. The regulated system voltage is determined by the voltage divider resistor values. Normally the remote pin voltage determines the value at which the battery voltage is regulated. In some cases the remote pin is not used. When this condition (VPin 2 < 0.6 V typically) exists, a sense loss function allows the local pin voltage to determine the regulated battery voltage with no attenuation of signal. If, however, when the remote pin is used, and the voltage at this pin is approximately 25% less than the voltage at the local sense pin (but greater than 0.6 V, typically), the value at which the battery voltage is regulated is switched to the local sense pin voltage (minus the 25%). The signal combiner/switch controls this transfer function. Low Pass Filter, DAC & Regulator Comparator The output of the combiner/switch buffer feeds a low pass filter block to remove high frequency system noise. The filter output is buffered and compared by the regulator comparator to a descending ramp waveform generated by an internal DAC. When the two voltages are approximately equal, the output of the regulator comparator changes state and the gate of the MOSFET is pulled low (turned OFF) by the output control logic for the duration of the output frequency clock cycle. At the beginning of the next output clock cycle, the DAC begins its descending ramp waveform and the MOSFET is turned ON until the regulator comparator output again changes state. This ongoing cycle constitutes the PWM technique used to control the system voltage. Oscillator The oscillator block provides the clock pulses for the prescaler–counter chain and the charge control for the charge pump circuit. The oscillator frequency is set by an external resistor from Pin 7 to ground as presented in Figure 6. The prescaler–counter divides the oscillator frequency by 212 (4096) and feeds it to the output control logic and divider–up/down counter chain. The output control logic uses it as the fundamental regulation output frequency (Pin 17). Load Response Control The Load Response Control (LRC) circuit generates a digital control of the regulation function and is active when the stator output ac signal (Pin 10) frequency is lower than the Low/High RPM transition frequency. The LRC circuit takes the output signal of the prescaler–counter chain and with a subsequent divider and up/down counter to provide delay, controls the alternator response time to load increases on the system. The response time is pin programmable to two rates. Pin 11 programs the divider to divide by 12 or divide by 48. If Pin 11 is grounded, the signal fed to the up/down counter is divided by 12 and the response time is 12 times slower than the basic analog response time. If Pin 11 is left floating, the signal to the up/down counter is divided by 48 and the response time is 48 times slower. The basic analog (LRC not active) and digital duty cycle control (LRC active) are OR’d such that either function will terminate drive to the gate of the MOSFET device with the shortest ON–time, i.e., lower duty cycle dominating. 7 MC33092A The digital ON–time is determined by comparing the output of the up/down counter to a continuous counter and decoding when they are equal. This event will terminate drive to the MOSFET. A count direction shift register requires three consecutive clock pulses with a state change on the data input of the register to result in an up/down count direction change. The count will increase for increasing system load up to 100% duty cycle and count down for decreased loading to a minimum of 29% duty cycle. The analog control can provide a minimum duty cycle of 4 to 5%. The initial power–up duty cycle is 29% until the phase comparator input exceeds its input threshold voltage. Also, the IC powers up with the LRC circuit active, i.e., when the Lamp Collector pin exceeds the power–up threshold voltage. Fault Lamp Indicator Pins 3 and 4 control the external Darlington transistor (Q2) that drives the fault indicator lamp. A 10 Ω resistor should be placed in series with the transistor’s emitter for current limiting purposes. The fault lamp is energized during any of the following fault conditions: 1) No Phase buffer (Pin 10) input due to slow or no alternator rotation, shorted phase winding, etc.; 2) Phase buffer input ac voltage less than the phase detect threshold; 3) Overvoltage on Pin 2, or Pin 12 if Pin 2 is not used, or 4) Undervoltage on Pin 19 with the phase buffer input signal higher than the Low/High RPM transition frequency. Phase Buffer Input A tap is normally connected to one corner of the alternator’s stator winding to provide an ac voltage for rotation detection. This ac signal is fed into the phase buffer input (Pin 10) through a voltage divider. If the frequency of this signal is less than the phase rotation detect frequency (36 Hz, typically), the fault lamp is lit indicating an insufficient 8 alternator rotation and the MOSFET drive (Pin 17) output duty cycle is restricted to approximately 29% maximum. Also, if the peak voltage of the ac signal is less than the phase detect threshold, the fault lamp is lit indicating an insufficient amount of field current and again the MOSFET drive (Pin 17) output duty cycle is restricted to approximately 29% maximum. Undervoltage, Overvoltage and Load Dump The low pass filter output feeds an undervoltage comparator through an external voltage divider. The voltage divider can be used to adjust the undervoltage detection level. During an undervoltage condition, the fault lamp will light only if the phase buffer input signal frequency is higher than the Low/High RPM transition frequency. This is to ensure that the undervoltage condition is caused by a true fault and not just by low alternator rotation. To help maintain system voltage regulation during an undervoltage condition, the output duty cycle is automatically increased to 100%. Even though the fault lamp may be energized for an undervoltage condition, the MC33092A will continue to operate but with limited performance. Through an internal voltage divider, the low pass filter feeds an overvoltage comparator which monitors this output for an overvoltage condition. If the overvoltage threshold is exceeded, the fault lamp is lit and the MOSFET drive (Pin 17) output duty cycle is restricted to approximately 4% maximum. The internal voltage divider on the input to the load dump comparator has a different ratio than the divider used on the overvoltage comparator. This allows the load dump detect threshold to be higher than the overvoltage threshold even though both comparators are monitoring the same low pass filter output. If the load dump detect threshold is exceeded, the fault lamp and MOSFET drive outputs are disabled to protect the MOSFET, field winding and lamp.
