NOTES :
1.
For pins 1 and 6 the values of voltage and current stated are interdependent
2.
The maximum power dissipation is a function of the ambient temperature and the thermal
resistance. The maximum power dissipation is calculated as follows :
(VS - VCC) * IOUT+ PBUS ≤ PTOT, max
Where PBUS is the bus driver component. Power dissipation is typically < 25mW
3.
See Over temperature circuit.
2.2
Recommended Operating Conditions
The following conditions apply unless otherwise stated.
All of the following parameters are valid for an operating temperature range of -40°C up to 125°C and a
supply voltage range of 4.75V < VCC < 5.25V and 5.25V < VS < 40.0V, unless otherwise specified.
Voltage reference is GND, if not otherwise specified. The current values are positive, if flowing into the
circuit.

Detailed Functional Description
The 910.45 integrated interface is designed for the control of serial data channels. The circuit realizes the
translation of transmit and receive signals from the processor voltage to the 12V bus level.
Undefined states are avoided during low voltage conditions by means of a Power-on-Reset which
connects and disconnects the outputs and inputs. The inputs make use of internal Pull-up and Pull-downresistors to maintain defined levels.
The bus control pin BUS can operate from voltages between GND +40V and less than GND -36V. This
ensures that an open circuit ground connection or power supply interruption does not inhibit the operation
of other devices using the bus.

Voltage Regulator with LIN-Bus Interface
and 4.1V Reset
QMNr.:03SP0073E.00
Date :14.02.2003
SPECIFICATION
4.2.1 Transmitter Path
A Low level on the TXD pin switches the open-collector transistor on the Bus Pin on. In order to minimise
the EMC radiation on the bus, the rise and fall time of the transmit pulse on the Bus pin is conditioned by a
slew rate controller.
4.2.2 Receiver Path
The signal on the BUS pin is permanently available at RXD (VCC>VRES1). Transients are filtered by an
internal delay of typ. 3µs on the comparator input.
4.2.3 Stby -Mode
The circuit turns on automatically after the battery voltage (VS) is greater than VSENSEH . After this it is
necessary to set EN to a voltage greater than VENH before it is possible to disable the circuit.
A voltage smaller than VENL at the Pin EN, switches the voltage regulator off (stby-mode). In this mode the
current consumption is smaller than 50µA. As long as the circuit operates in stby mode the EN input is
held to GND via an internal pull down current of typ. 100µA. It can be switched on again by setting VEN at
a voltage greater than VENH. The pull down current at the Pin EN is reduced to 4µA (see 3.1 Nr 25)
If the circuit operates in stby-mode it can also be switched on by a level change of typically 45µs on the
Pin BUS.
4.2.4 Temperature Protection
The over temperature protection operates between Tj = 150°C and Tj = 170°C. In the range 150°C to over
temperature shut off the principal functions of the device are maintained within specification. The over
temperature protection circuit disables the output voltage and the bus driver. When the temperature
returns to the normal operating level, a reset signal is generated.
When Tj is typically 140°C the device operates again with a normal reset signal, independent of EN and
BUS level. The over temperature protection can be tested over the Pin TEST. This Pin has to be set to
GND in application.
4.2.5 Initialisation
Switch on of VS, switch on after over temperature protection and recognition of an edge on the bus:
The Bus is active when VCC exceeds VRES1 (typically. 3.15V). The internal reset logic is in a shut down
condition. The voltage regulator is in a switch on condition and can be switched off by a high/low
transition of the EN pin.
4.2.6 RESET Programming
The VTR pin allows programming of four different modes of the RESET function. With VTR tied to GND
the low RESET threshold (VRES1 = 3.15V) is valid, and when VTR is tied to VCC the high RESET
threshold is valid (VRES2 = 3.95V).
When VTR is tied directly to VCC or GND a RESET time of 100ms is valid. When VTR is tied to VCC or
GND via a resistor of minimum 50kOhm, a RESET time of 15ms is valid.
The VTR programming takes place during the first oscillator period and will be fixed until Vbat turns off.
When the system is powered up the high threshold VRESON is always valid. The RESET function is
referenced to VCC.
The RESET function is interrogated in the following manner: Following the crossing of the reset threshold
VRESON the potential on VTR is interrogated. Depending upon the result of this interrogation following
the first clock pulse after the RESET the pull up or the pull down current source is activated for one clock
pulse. In this time the potential on the VTR pin changes if it is tied to VCC or GND via a 50kOhm resistor.
From this information the Reset time can be determined.

4.2.7 Transient Resistance
Transients (1, 2, 3a, 3b, 100V, -150V) are coupled to the BUS pin without special filter elements. The
transient impulses have no influence upon the inner state or the outputs of the device.
The transients are also coupled to VS by the application circuit wherein a 47nF and a 100uF capacitor with
an ESR of 7 Ohm is used. The function of the capacitor is to flatten the transient inpulse.
An extra slow diode (e.g. D1F-60 or BYM 10 600) is used. Thus the internal condition of the device cannot
be altered; the device must maintain specified conditions.
The relatively high specified maximum Latch up current on VS enables the device to operate with a
resistor and a capacitor, but without polarised protection diode (zener?), so that the external circuitry
limits of -500mA or -1V bz. +40V are not exceeded.
The transients 3a and 3b are fed directly to VS, since VS is blocked with a 47nF capacitor to GND there
can be no disturbance of the internal condition of the device.
During test the EN-Pin is tied to VS. For the pins EN and SI care has been taken to ensure that when the
transient arrives at these pins (Singly, or tied together) via a 10kOhm resistance that no disturbance of the
internal condition occurs. A clamp current of +-10mA on these pins causes no alteration in the function of
the device.
Voltage spikes on VS within the operating voltage range have no short term influence on the voltage value
at VCC, when they are below VRES1 or over 5.25V.
4.2.8 Output Circuit
The voltage regulator is stable with an output capacitance of min. 1µF. The selection and value of the load
capacitance can be selected depending upon the application ( e.g. 4.7 µF Tantal ), so that the important
parameter the current difference during load changes as well as the maximum permitted short term
voltage breaks.
4.2.9 Under Voltage
In the range 4.5V < VCC < 5.25 The Bus interface operates within the specified parameters. In the range
VRES1 < VCC < 4.5V the TXD-Signal is sent to the Bus; the receive path is also active. In the range VCC
< VRES1 the Bus driver remains in a high impedance condition. SENSE and SO also generate (VCC >
VRES) further correct signals; the specification of the input threshold of SI will eventually no longer be
met.
4.2.10 Short Circuit Capability
All inputs and outputs are short circuit protected to VCC und GND. In addition, VCC and BUS are
protected against over temperature. In the event of a short circuit on VS, the capacitance on VCC is
discharged via the reverse diode of the regulator transistors. The discharge current is conducted to a
capacitor of 1000uF to prevent damage to the regulator. The current from VCC to VS has no effect on
functionality of the device (RESET, BUS) (the Bus does not enter a low resistance condition, and, RESET
is still correctly generated etc.).
4.2.12 Baud Rate
The device is designed to operate with a nominal transfer frequency of 20000 Baud (CBus < 25nF). Due to
the symmetrical delay times the device can operate in certain special modes (i.e. Programming of flash
memory) with higher Baud rates.
4.2.13 Reset
The Power On Reset has no hysteresis.
