DESCRIPTION

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).
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.
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.

Lamp Base
The Lamp Base pin provides base current to the fault lamp drive transistor
(Q2).
Grounded to provide a ground return for the fault lamp control logic circuit.
IC ground reference pins.
A resistor to ground on this pin adjusts the internal oscillator frequency.

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.
Oscillator Test point for checking the operation of the internal oscillator.
The Phase input detects the existence of a magnetic field rotating within the
alternator.
The Rate pin is used to select a slow mode (floating) or fast mode (ground)
Load
Response Control recovery rate.
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.

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.
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.
Controls the Gate of the MOSFET used to energize the field winding.
Field winding control MOSFET source reference.
