TYPICAL APPLICATIONS
INTRODUCTION
The 33099 is an alternator voltage regulator designed with
internal level shifting resistors to control the voltage in a 12 V
automotive system that uses a three-phase alternator with a
rotating field winding. The system shown in Figure 4 includes

Figure 4. 33099 Simplified Application
The 12 V system voltage (V BAT ) is connected to a
REMOTE input by a remote wire, which provides the IC
regulator with an external Kelvin connection directly to the
battery to provide REMOTE voltage, V rem . The system
voltage at the BAT pin is also sensed by an internal Local IC
connection as Local voltage V l . The Local connection is
provided in the event the remote wire or remote connection
becomes faulty such as being resistive, an open, or shorted
to ground.
The PHASE input is normally connected to a tap on one
corner of the alternator's stator winding, which provides an
AC phase voltage (V ph ) for the IC to determine the rotational
frequency (f ph ) of the alternator rotor. Two frequency
comparators (F1 and F2) monitor voltage V ph to determine a
phase rotation detection frequency (f 1 ) and a Low/ High RPM
transition phase frequency (f 2 ), respectively. A PHASE
FILTER pin is provided for externally providing a filter
capacitance for filtering phase input noise.
The regulated DC system set voltage (V set ) is achieved by
employing feedback to compare a ratioed value of V set to an
internal IC bandgap voltage reference having a negative
temperature coefficient (TC). The GATE drive of an external
N-channel MOSFET is regulated by the IC to control the field
current in the alternator field coil as an alternating ON or OFF
state dependent on load current conditions affecting voltage
V set . The external MOSFET receives GATE-to-source
voltage drive from between the GATE and SOURCE output
pins of the IC. The GATE-to-source voltage is a Pulse Width
