PIN FUNCTIONS
N
°
Name
Functions
1
Alternator Voltage
Sensing
Connection for voltage regulation sensing. The regulation sensitivity is a
function of R1 and is given by :
S =
VA
R1
= 0.5mV
2-3
Filter Capacitor
A capacitor connected between these two pins filters the feedback signal from
the regulated output. Typically the input impedance is 15K
.
4
Alternator Overvoltage
Adjustment
When this pin is left open circuit the overvoltage threshold is a described in the
specification. Typically the warning lamp is switched on when the voltage at
this pin is greater than 3.5V. This threshold can be modified with a resistor
between either the ground or pin 2.
5
GND
This pin must be connected to ground.
6
Darlington Driver
This pin drives the external darlington disabling it by shorting the current in RB
to ground.
7-8-9
N.C.
These pins must be left floating.
10
IC Supply Voltage
Supply Voltage Input
A 7.5V (typical) Zener is present at the input.
11
Oscillator Capacitor
A capacitor connected to ground sets the frequency of the internal oscillator.
The frequency is given by :
fosc =
20 x 10
6
8.4
x Cosc
12
GND
This pin must be connected to ground.
13
Lamp Driver
Current Driver for External Lamp for Diagnostics.
Internally protected agains short circuits (current limiting), load dump transients
and, by means of a zener, against low energy spikes.
14
NC
Not connected.
15
Phase Voltage Sensing.
Connection for no charge sensing from the alternator .
The internal low threshold is typically 2.4V. By means of the external divider
R3/R4 the threshold can be adjusted to give the required sensitivity.
16
Battery Voltage Sensing
Connection for Voltage Battery Sensing
This pin senses a failure of the alternator-battery lead as the voltage difference
VA-VS. The external resistor R2 limits the current in overvoltage protection.
