LINEAR INTEGRATED CIRCUIT
APPLICATION NOTES
This UTC ULN202 has no protection functions for over-current and over-voltage. If the applied situation includes
over-current or over-voltage, this IC may be destroyed. We should take care of the systems design with this IC. The
OUTPUT, COMMON and GND lines should be designed carefully，because the IC may be destroyed due to
short-circuit between outputs, air contamination fault, or fault by improper grounding.
The UTC ULN202 is a darlington driver array. When it is applied with a general logic circuit such as TTL or CMOS,
resistors should be connected in series to every input to achieve a stable input current.
When the load is connected between the output and the power supply, the COMMON pin should be shorted to the
power supply to protect the IC from extra swing voltage.
NOTICE ON PRODUCT USE
(1) The absolute maximum ratings should be not exceeded, even for a moment, otherwise the device may be
breakdown, damaged or deteriorated, and even injury by explosion or combustion.
(2) The power supply fuse should be used to prevent a continuous large current from the over current situation
and IC failure. The improper wiring layout and an abnormal pulse noise from the wiring or load both can cause a
large continuous current and even the breakdown, and finally can lead smoke or ignition. So we should design
carefully considering fuse capacity, fusing time and insertion circuit location, the effects of a large current can be
improved.
(3) When the inductive load is applied such as motor coil, it can cause the device malfunction or breakdown due to
the current resulting from the inrush current at power ON or the negative current resulting from the back
electromotive force at power OFF, so a protection circuit should be designed. When using build-in protection
functions IC, a stable power supply is required, otherwise the protection function may not operate and cause IC
breakdown. IC breakdown may result injury, smoke or ignition.
(4) The devices should not be mounted in the wrong orientation or incorrectly, and the positive and negative
terminals of power supplies should also are connected properly, otherwise the current or power consumption may
exceed the absolute maximum rating, also it may cause the device breakdown, damage or deterioration, and may
result injury by explosion or combustion. In addition, any device should not be used when it is applied the current
with mounted in the wrong orientation or incorrectly even just one time.
(5) The careful selection of external components is also important, such as inputs and negative feedback
capacitors, load components (such as speakers), power amp and regulator. If a large leakage current flow the input
or negative feedback capacitors, the IC output DC voltage will be increased. If this output voltage is connected to a
speaker with low input withstand voltage, the smoke or ignition can be caused for over-current or IC failure, even the
smoke or ignition from the IC itself. In addition, please also pay attention to the Bridge Tied Load (BTL) connection
type IC that inputs output DC voltage to a speaker directly.
POINTS TO REMEMBER ON PRODUCT USE
(1) Heat Dissipation Design
An inadequate IC heat dissipation design can reduce the IC life, deterioration of IC characteristics, even IC
breakdown. When the IC is applied with a large current flow such as power amp, regulator and so on, the careful
heat dissipation design should be implemented, not to exceed the maximum ratings of junction temperature (Tj).
Meanwhile, also please pay attention to the effect of IC heat dissipation on peripheral components.
(2) Back-EMF
Being the effect of back-EMF, a current can flow back to the motor’s power supply when a motor rotates in the
reverse direction, stops or slows down suddenly. If the power supply has a low current sink capability, the device’s
motor power supply and output pins might be influenced for excessing the absolute maximum ratings. In the system
design, we should take the effect of back-EMF into consideration to avoid the accident.
