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
5.1
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
5.2.1
PHASE (PH1 and PH2)
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.
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).

LIN BUS (BUS)
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.
5.2.3
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.
Note: The PGND, the SGND pins must be connected together to a ground external to the device.
5.2.4
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.
5.2.5
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.

5.3.1
SUPPLY VOLTAGE: Filter/Divider, Bandgap, and POR
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.
5.3.2
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.
5.3.3
LOGIC AND CONTROL
DIGITAL
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).
A/D CONVERTER
The analog to digital converter is used in the voltage regulation loop, in the current feedback and in temperature measurement.
LIN
This block allows the LIN bus transmission and reception.
T° MEASUREMENT
This block generates a voltage proportional to the die temperature. This voltage is converted by the ADC into a digital number to be
transmitted via the LIN bus to the controller.

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

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).
5.6.4
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 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.
5.6.5
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.

5.6.6
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. B+A is lower than VREG. In any case, DC cannot be lower than DCMIN.

This state machine runs only if self-start option has been programmed.
5.6.7
Standby
The 80310 is in Standby mode if there is a LIN timeout, and in absence of alternator rotation (no phase), if 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

5.6.8
Wake-up
This state is reached when an edge is detected on the phase (Phase voltage > Phase sensitivity)
• The logic is out of reset
• 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.
5.6.9
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 self-start 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.
5.6.10 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.
5.6.11 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.
5.6.12 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.
5.6.13 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
Table 10 lists the values for the Target/Programmed Regulated voltage contained in the Alternator A/B write data field (ID=29, 2A), byte 1.

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.
18. This gives a resolution of 3.5 degrees and the accuracy is +/-10 degrees. Excitation Current and Die Temperature functions are exclusive.

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
5.9.1
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”.
5.9.2
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.
5.9.3
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.
5.9.4
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.
5.9.5
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
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.

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.
