1.Overview
The OL7272 is an industrial power line driver and contains four identical short circuit proof differential line
drivers up to 30 Volts driver supply with a joint enable function. At overload there is a thermal shutdown
feature which can be disabled by the user. The high data rate and immunity to cable inductance and
capacitance makes an ideal linedriver.
The very small outline SOP package gives excellent thermal power dissipation, thus the usage in
space limited applications is easy.

Functional description
The main contents of this new CMOS power line driver are four identical blocks (systems A to D)
with each a CMOS/TTL Schmitt Trigger Input (can be driven at up to VCCD as well) and high power
differential buffered and inverted outputs. With the low active ENABLE pin it is possible to switch off all
eight outputs (high-impedance state), thus this driver can be used in industrial bus systems.
In some rare applications it might be useful to disable the overtemperature shutdown. This can be done
by setting the ENABLE pin to a level between >7,5 V and <12 V. In this case the whole protection of the
IC is disabled! In case of any short circuits or thermal overdrive, the driver might be destroyed!
An internal ultra low drop voltage regulator with typical 5.0 V supplies the internal logic to reduce power
dissipation.
The over-temperature protection block is placed in the center of the chip. The thermal shutdown will be
activated, when an overload condition (i.e. short circuit) has exceeded the over-temperature detection
threshold. In this case automatically all output drivers are switched off. After the chip has cooled down
(a few milliseconds) it automatically re-activates all functions. In case the short circuit is still present, it
switches off again and the same cycle starts from the beginning.
By using this line driver, the field returns of systems, which are accidentally shorted and blown by the
end users, are dramatically reduced.
The OL7272 is pin compatible to a couple of popular other line drivers like 26xx31, ET7272 etc.
Power supply
The internal power supply is designed as a voltage regulator with a typical output voltage VCCI = 5.0 V.
The minimal voltage drop across the regulator transistors could not be lower than 0.3 V.
Under-voltage reset
If the system is switched on, the status of the line driver is, for a few microseconds, undefined. The
same happens, if heavy power supply failures occur. To avoid wrong data transmitted, there is a supply
voltage watchdog implemented.
If the system is switched on, the status of the line driver is, for a few microseconds, undefined. The
same happens, if heavy power supply failures occur. To avoid wrong data transmitted, there is a supply
voltage watchdog implemented.
The under-voltage reset block contains a comparator. The voltage VCCI will be always compared with a
reference voltage, provided by an internal bandgap cell. If after a filter time (tFILLVR ~ 5 μs) VCCI drops
below the typical voltage threshold of 3.5 V the output signal of this block switches off all output drivers
to the high-impedance state until minimum 3.6 V are reappearing.

ESD / EMI
The chip is an ESD sensitive device and should be handled according to guideline EN100015 / part 1
(„The Protection of ESD Sensitive Devices„).
All pins are ESD protected according to ESD standard MIL883, method 3015.7 (human body model).

General Description
The OL2068LF is an industrial
power line driver and contains
four identical short circuit proof
differential line drivers up to 30
Volts driver supply with a joint
enable function. An internal 5 V
power supply is used as
reference and supply voltage for
the circuitry and is able to supply
max. 5mA for external 5V
components like a sensor, or a
constant current source for a
LED.
The very small outline TSSOP
package gives excellent thermal
power dissipation, thus the usage
in space limited applications is
easy.

impedance.

Application notes
For differential line driver applications it is recommended to use shielded twisted pair cable. Unfortunately
this type of cable is not widely used. A more realistic load circuit is therefore shown in Figure 12. A long
cable model is shown in Figure 13.
