Alternator Regulator with LIN
80310
The 80310 is an integrated circuit intended to regulate the output
voltage of an automotive alternator.
The IC supplies a current via a high side MOSFET to the excitation
coil of the alternator and provides an internal freewheeling diode. It
keeps the battery at its nominal charge and delivers current to
electrical devices within the vehicle.
The 80310 also provides a load response control mechanism
(LRC), and has an interface for the industry standard LIN protocol
(Revision 1.3) to allow an ECU to control the regulated voltage and the
LRC rate among other parameters. The ECU also can read back
information about the status of the regulator and the alternator via LIN.
It can be programmed for most functions using OTP (Non-volatile
Memory) and fit a large number of alternators and applications.

FUNCTIONAL DESCRIPTION
INTRODUCTION
FUNCTIONAL DESCRIPTION
INTRODUCTION
The 80310 is an integrated circuit intended to regulate the
output voltage of an automotive alternator.
The IC supplies a current via a high side MOSFET to the
excitation coil of the alternator and provides an internal
freewheeling diode. It keeps the battery at its nominal charge
and delivers current to electrical devices within the vehicle.
The 80310 also provides a load response control
mechanism (LRC), and has an interface for the industry
standard LIN protocol (v1.3) to allow an ECU (master) to
control the regulated voltage and the LRC rate among other
parameters.
The ECU also can read back information about the status
of the regulator and the alternator via LIN.
The programmable parameters by the ECU:
• Regulated voltage
• LRC ramp time, LRC cut off
• Excitation current limitation
The information sent back to the ECU:
• Die temperature
• Excitation current
• EXC duty cycle (DF)
• Manufacturer and class
• Faults:
•Electrical, mechanical, temperature
•LIN time out
•LIN communication error: watchdog, check sum, Id
parity, sync break
The IC can be programmed as an OTP device (One Time
Programmable) to fit a large number of alternators and
applications. These programmable parameters are described
in the functional device operation (Table 6). This circuit is
specially designed to operate in harsh automotive
environment.
FUNCTIONAL PIN DESCRIPTION
PHASE (PH1 AND PH2)
LIN BUS (BUS)
These pins connect to stator windings. These signals are
used for the rotor speed measurement, stator voltage
measurement as well as the self start detection.
This LIN pin represents the single-wire bus transmitter and
receiver. It is suited for automotive bus systems and is based
on the LIN bus specification v1.3.
GROUND PINS (PGND, SGND)
The 80310 has two different types of ground pins. The
PGND pin is the power ground pin for the device. The SGND
is the signal ground pin.
Important: The PGND, the SGND pins must be connected
together to a ground external to the device.
SUPPLY VOLTAGE (B+A)
The 80310 is supplied by this B+A pin. This voltage is also
used as the feedback voltage by the control circuit.
Figure 6. Internal Signals in Normal Mode
In this situation the regulator stays in Normal mode. (P1
and P2 represent internal signals coming from the phase
processor block, which are routed to the logic block).
EXCITATION (EXC)
This pin is connected to the excitation coil (rotor) of the
alternator. The IC supplies a current via a high side MOSFET
to the excitation winding to create a magnetic filed in the
rotor. This generates sinusoidal currents in the stator which
are rectified by a diode bridge.

SUPPLY VOLTAGE: FILTER/DIVIDER, BANDGAP,

LOGIC AND CONTROL:
An input filter and divider provides a clean image of the
battery to the digital regulation loop circuit. The divider ratio
can be adjusted by OTP.
The supply block provides the voltages for the internal
blocks of the 80310:
• Main logic
• Analog permanently powered or not
• LIN transceiver
• Charge pump
The purpose of the POR block is to generate a clean
power-on signal to the main logic.
The Bandgap block provides the voltage and current
references for the other blocks.
DIGITAL
POWER STAGE: CHARGE PUMP, DRIVE AND
PROTECTION, CURRENT MEASUREMENT
The power stage of the circuit consists of the gate driver
with a charge pump and protection to control a low side driver
switching the excitation current. A short-circuit is
instantaneously detected and the excitation current is turned
off until the next regulation cycle. A freewheeling diode is
inserted between the EXC and GND pins, across the
excitation coil for the energy recirculation.
The current measurement block provides a proportional
value of the excitation current flowing in the high side switch.
The digital block gathers all the digital functions of the
device. The main functionality is described in the device
operation paragraph.
CLOCK
This block is the clock reference for the digital block. The
oscillator generates a 5.0 V square wave at the frequency of
4.0 MHz in Normal mode operation.
OTP
This block allows an easy configuration and adjustment of
the circuit. A set of NVM bits can be programmed during the
factory test phase. They are described in Table 6.
PHASE LOW & HIGH
The phase detector monitors the Phase inputs and sends
filtered low and high levels to the main logic when either one
has reached the detection level (1.0 V at startup and 8.0 V
afterwards).
ADC
The analog to digital converter is used in the voltage
regulation loop, in the current feedback and in temperature
measurement.

STANDBY:
The 80310 is in standby mode, if there is a LIN timeout and
in absence of alternator rotation (no phase), or in case of
power and reset (POR), or with a LIN MID3C command if
nvm_lin_special is set
• There is no excitation.
• The duty cycle (DC) is equal to zero.
The device needs a small amount of quiescent current to
feed some functions such as oscillator.
LIN timeout means:
• No activity on the LIN bus during a specified time
• or on a LIN watchdog timeout during a specified time
WAKE-UP:
This state is reached when a transition is detected on the
communication interface.
• The logic is out of reset.
• All the blocks are on.
• There is no regulation. DC = 0%
After a LIN timeout, if no valid instruction is decoded, then
the device goes back into Stand-by mode.
PRE-EXC:
The pre-excitation state is reached as soon as a valid
instruction for the regulated value (VREG), different from
10.6 V, is decoded.
If B+A is lower than the expected (VREG), then the duty
cycle is equal to DCSTART UP, or else DCMIN.
The purpose of pre-excitation is to increase the
magnetization of the alternator, to guarantee a minimum
phase voltage for the rotor speed measurement when the
engine starts.
The pre-excitation stays active until the detection of phase
starts regulating RPM (fSTART).
REGULATION WITH LRC:
In this mode, the 80310 regulates the alternator output to
the set reference level. The excitation is controlled by LRC if
this LRC mode is active until the detection of phase stop This

stop regulating RPM, the device goes to pre-excitation mode.
LRC mode is active until the detection of phase stop
regulating RPM (fSTOP). In this case, the device goes back to
the pre-excitation mode. If the phase frequency reaches the
LRC disable RPM default (fLRC), the device goes into
regulation without LRC.
RE-REGULATION:
The excitation is forced to 100%. This mode is active if
there is no high phase on non active phase (PHx < VPH) in
the previous cycle, until the high phase comes back. At the
end of the 8th cycle, if there is still no high phase, the
regulation mode is set off and the device goes back to the
regulation mode with or without LRC.
REGULATION WITHOUT LRC:
This mode is active when the phase frequency is above
the LRC disable RPM default (fLRC), the first VREG was
reached with LRC.
The excitation is controlled only by the internal comparator
of B+A and VREG. The DC can not be lower than DCMIN.
If the phase frequency goes below the LRC disable RPM
default (fLRC), then the 80310 comes back to the regulation
B+A is lower than VREG. In any case, DC cannot be lower
than DCMIN.

LIN timeout means:
STANDBY:
• No activity on the LIN bus during a specified time
The 80310 is in Standby mode if there is a LIN timeout,
• or on a LIN watchdog timeout during a specified time
and in absence of alternator rotation (no phase), if power and

FUNCTIONAL DEVICE OPERATION
STATE MACHINE
• All the blocks are on
• There is no regulation. DC=0%
After a 100 ms timeout, if the speed has not reached
fSTART, then the device goes back to Standby mode.
EXCITATION 100% DC:
When the speed has reached Start_aa, then the device
goes into this state until the high phase appears, or during a
100 ms maximum.
• The logic is out of reset.
• All the blocks are on.
• There is no regulation. DC = 100%
Start_aa (see Table 1): is a special threshold for the selfstart when it is in Wake-up mode, before going in EXC 100%
DC, waiting for high phase. Once high phase appeared the
state machine is exactly the same as with LIN wake-up
Start_aa can be programmed at 3000 rpm or 4000 rpm.
REGULATION WITH LRC:
In this mode, the 80310 regulates the alternator output to
the set reference level. The excitation is controlled by LRC, if
B+A is lower than VREG. DC can not be lower than DCMIN.
This LRC mode is active until the detection of phase stop
regulating RPM (fSTOP). In this case, the device goes back to
the Pre-excitation mode. If the phase frequency reaches the
LRC disable RPM default (fLRC), the device goes into
regulation without LRC.
REGULATION WITHOUT LRC:
This mode is active when the phase frequency is above
the LRC disable RPM default (fLRC), the first VREG was
reached with LRC.
The excitation is controlled only by the internal comparator
of B+A and VREG. The DC can not be lower than DCMIN.
If the phase frequency goes below the LRC disable RPM
default (fLRC), then the 80310 comes back to the regulation
with LRC mode. If the phase frequency goes below the phase
stop regulating RPM, the device goes to Pre-excitation mode.
RE-REGULATION:
The excitation is forced to 100%. This mode is active if
there is no high phase on non active phase (PHx < VPH) in
the previous cycle, until the high phase comes back. At the
end of the 8th cycle, if there is still no high phase, the
regulation mode is set to off and the device goes back to the
regulation mode, with or without LRC.
LIN BUS INFORMATION:
The operational control and programming, required in the
end application, is carried out through the LIN interface. Refer
to Tables 7 to 15.
The regulator shall only give pre-excitation when it
receives a LIN command targeted for it, the shutdown
command is the code that would otherwise set 10.6 V
(“000000”).
LIN addresses are listed in MID format, Table 8, while the
data fields are listed in [MSB:LSB] format

17. This information is given as 6 bits and is only accurate:
a) from 0 °C to 25 °C:
- from 0 A to 3.875 A: +/- 375 mA
- from 3.875 A to 7.75 A:+/- 10%
b) outside the previous temperature range:
- from 0 to 3.875 A: +/-625 mA
- from 3.875 A to 7.75 A: +/-15%
Currents higher than 7.75 A, which may be possible at low temperature, are reported as 7.75 A. Excitation Current and Die Temperature
functions are exclusive.

FUNCTIONAL DEVICE OPERATION
THERMAL COMPENSATION
THERMAL COMPENSATION
This function is activated when internal temperature is
above thermal threshold (135,145,150, or 160 degrees). In
this case, the V setting fixed by the LIN or by default is
compensated to reduce internal temperature. The de-rating
is calculated depending on the 4 categories of V setting.

PROTECTION AND DIAGNOSIS FEATURES
PROTECTION AND DIAGNOSIS FEATURES
FAULT DETECTION
General Notes
All fault reporting passes through a 400 ms digital filter to
avoid false indication problems, and transition from one fault
type to another should be “clean”.
MECHANICAL FAULT (F_MEC)
The Phase is off (Low Phase RPM below stop_regulation
threshold). Reported in Alternator A/B read data field (ID=11,
13), byte 1.
ELECTRICAL FAULT (F_EL)
If one of these faults appear:
• The number of “1”s in all the OTP bits, NVM[80:1] is not
ODD. The parity bit is included in the calculation
• The Phase is on (Low Phase RPM above
stop_regulation threshold) but High Phase 1 is not
detected
• B+A reaches 16.5 V with EXC at 100% DC
• Short circuit excitation load
• B+A stays at 75% of the target voltage when LRC is off
Note: This 5th additional condition is enabled only when
the NVM bit “Low Voltage Threshold” is enabled. Reported in
Alternator A/B read data field (ID=11, 13), byte 1.
ELECTRICAL FAULT (HP MASK)
A fault detection when High phase signal is cut is reported
on the electrical fault.
Option (OTP) available to remove this fault detection.
THERMAL FAULT (F_HT)
A thermal fault is reported when the die temperature
exceeds the programmed threshold. Reported in Alternator
A/B read data field (ID=11, 13), byte 1.
The programmed threshold in hexadecimal corresponds
to the following temperature in degrees:
• 6'b110010;//135degres
• 6'b110100;//145degres
• 6'b110110;//150degres
• 6'b111001;//160degres
ADDITIONAL ERRORS
LIN Bus Timeout
Check two timeouts:
• Activity on RXD is below 3 or 8 seconds (depending on
the OTP bit)
• Time between two consecutive valid messages is below
3 or 8 seconds (depending on the OTP bit)
This flag is reset once the microcontroller sends MID 11 for
ALTA, or MID 13 for Alt B. Reported in Alternator A/B read
data field (ID=11, 13), byte 2.
Comm Error
Checks the ID parity bits + Checksum byte + (TXD = RXD
when responding) + LIN Physical layout not in over-current
limitation. Reported in Alternator A/B read data field (ID=11,
13), byte 2.
LIN protocol errors:
• Sync Break Error: This flag is up when Synchro break
Field duration is lower than 10Tbits.
• Identifier parity Error: Comm error flag also reported in
MID11
• Checksum Error: Comm error flag also reported in
MID11
• Slave not responding Error: Tframe Max exceeded (LIN
Specification revision 1.3).
These flags are reset once the microcontroller sends MID
12 for ALTA, or MID 14 for Alt B. Reported in Alternator A/B
read data field (ID=12, 14), byte 2.

DIE CHARACTERISTICS
DIE CHARACTERISTICS
The die is designed to be fitted into a customer designed package, however as so many wiring configurations exist not all
may be possible from the same die design. Due to thermal considerations, soldering is the preferred die attach method, but under
some circumstances, conductive epoxy may be acceptable.

The fault detection when the high phase signal is cut, is reported on the electrical fault (if programmed, this part of the
electrical fault is masked)
Low voltage threshold: none
One pole Filter: No, default is 2 pole filter
Crest regulation: OFF
LIN Com with Global ID (MID 2B + 3C): OFF
CREST REGULATION
Crest regulation bit OFF: The product is in load dump mode. EXC is stopped when the internal filter reaches Load dump
detection threshold (21 V typ.). The delay is given by the internal filter (~1.0 ms).
Crest regulation bit is ON: The product is in crest regulation mode. EXC is stopped immediately when internal ADC reaches
21 V. The delay is given by the ADC (~16 µs).
For these two modes, Load Dump or Crest regulation, EXC is always OFF if the condition on B+A is present.
